Question

what is the surface area of a sphere with radius 2?

Answer 1

You can apply the formulae 4 pie r square

And you will get the answer 50.29

Answer 2

Answer:

Area of the sphere with radius 2 is 8π square units

Explanation:

Given Radius of a sphere (r) = 2 units

$\boxed {Surface\: area \: of \: the \: sphere(A)\\\\ = 4\times \pi\times r^{2}}$

Now ,

A = 4π×2²

=> A = 4π×4

=> A = 8π square units

Therefore,

Area of the sphere with radius 2 is 8π square units .
