How do you calculate the surface area of the moon?
1 Expert Answer area of any sphere is 4*pi*r^2 where r is radius of the sphere. Diameter of the moon is about 3500 km so its radius is about 3500/2=1750km and Moon’s surface area is about 4*pi*1750^2=3.85*10^7 square kilometers.
How do you find the surface area of a sphere with the diameter?
The formula of the surface area of a sphere in terms of diameter is given as, πD2 where “D” is the diameter of the sphere.
What is the diameter of moon?
2,159.1 miMoon / Diameter
Which formula is used to find the surface area of sphere?
4 π r2 square
A = 4 π r2 square units They are: Curved Surface Area.
What is moon surface?
The surface of the moon The moon’s surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for “seas” (maria when there are more than one).
What is diameter of a sphere?
The diameter of a sphere is the maximum distance between two antipodal points on the surface of the sphere. If is the radius of a circle or sphere, then . The ratio of the circumference of a circle or great circle of a sphere to the diameter.
How do you find the diameter of a sphere?
The diameter of a sphere can be found with the following equations:
- With given radius: d = 2 * r ,
- With given diameter: d = √(A / π) ,
- With given volume: d = ³√(6 * V / π) .
What is the ratio of diameters of moon and Earth?
The diameter of the moon is approximately one fourth of the diameter of the earth.
Is the moon 1/4 the diameter of Earth?
The Moon has approximately 1/4 Earth’s diameter, 1/50 Earth’s volume, and 1/80 Earth’s mass. Earth is very dense overall (it is the densest planet in the Solar System), but the Moon is light for its size.
Who found the diameter of the moon?
The jump Aristarchus made from terrestrial measurements of scale to the celestial is truly remarkable. Without any measures of the sizes of or distances to any celestial objects, he was able to measure both for the Moon.
What is the diameter of the moon compared to the earth?
Size: With a diameter of 2,159 miles (3,475 kilometers), the Moon is just 1/4 the size of Earth. Distance from Earth: The Moon’s average distance from Earth is 238,000 miles (383,500 km). Orbit around Earth: It takes the Moon 27.3 Earth days to revolve around our planet one time.
What are the 3 main surface features on the moon?
While the craters, highlands and maria are the moon’s three main landforms, the moon’s surface has a number of other highly visible features.
What is the surface of the moon made up of?
The average composition of the lunar surface by weight is roughly 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, 0.42% chromium, 0.18% titanium and 0.12% manganese. Orbiting spacecraft have found traces of water on the lunar surface that may have originated from deep underground.
What is the surface area of the sphere?
4*Pi*R2
And the formula for the surface area of a sphere of radius R is 4*Pi*R2.
What is the area of the sphere?
4πr²
Surface Area of Sphere = 4πr², where r is the radius of sphere. A sphere is a solid figure bounded by a curved surface such that every point on the surface is the same distance from the centre.
Does a sphere have a diameter?
The Diameter of a circle or sphere is equal to 2 times the Radius.
What fraction of Earth diameter is diameter of moon?
approximately one-fourth
The diameter of the moon is approximately one-fourth the diameter of the earth.
Is the moon 1/3 the size of Earth?
The moon is a bit more than one-quarter (27 percent) the size of Earth, a much larger ratio (1:4) than any other planets and their moons. Earth’s moon is the fifth largest moon in the solar system.
What is the surface area of the Moon?
The moon (at 38 million square meters) covers a little more than Africa (30 million square meters) and is about half the area of the Atlantic Ocean (77 million square meters). The surface area of a sphere is 4 pi.
What is the surface area of a sphere?
This is the total area of the surface of a sphere with the specified diameter. The sphere surface area represents the total area of the outer surface of the sphere if it was to be laid out flat as a two-dimensional shape, e.g. a true scale map of the world is a 2D scaled representation of the surface area of the world.
What is the diameter of the Moon compared to Earth?
The diameter of the Earth is 12,742 km, so the Moon’s diameter is about 1/4 that of the Earth (27.3% to be exact). Need another comparison? The diameter of Jupiter’s moon Ganymede – the largest moon in the Solar System – is 5,268 km across. This makes it about 1.5 times larger than the Moon.
The diameter of a sphere is the length of a straight line drawn between two points on the surface of the sphere, where the line also passes through the centre of the sphere. This is the total area of the surface of a sphere with the specified diameter.
