Question

The diameter of the Moon is 3480 km. What is the surface area of the Moon?

Answer 1

Answer:

Surface area of the moon is $S=3.8\times 10^{13}\ m^2$

Explanation:

It is given that,

Diameter of the moon, d = 3480 km

Radius of the moon, $r=1740\ km=1740\times 10^3\ m$

Moon is in the form of sphere. The surface area of the moon is given by :

$S=4\pi r^2$

$S=4\pi \times (1740\times 10^3)^2$

$S=3.8\times 10^{13}\ m^2$

So, the surface area of the moon is $3.8\times 10^{13}\ m^2$. Hence, this is the required solution.

Answer 2

We have that for the Question "The diameter of the Moon is 3480 km. What is the surface area of the Moon?" it can be said that the surface area of the Moon

A=38045943.67km

From the question we are told

The diameter of the Moon is 3480 km. What is the surface area of the Moon?

 

Generally the equation for the   surface area of a Sphere is mathematically

given as

$A=4\pir^2\\\\Therefore\\\\A=4\pir^2\\\\A=4\pi( 3480 /2)^2$

A=38045943.67km

Therefore

the surface area of the Moon

A=38045943.67km
