Question

Can anybody help me on this

Answer 1

The correct answer is second option

256 π in² (it is surface area not the volume)

Explanation:

Formula

Surface area of sphere = 4π r²

Where r is the radius of the sphere

From the figure we can see a sphere with radius = 8 inches

To find the surface area of sphere

Here r = 8 inches

Surface area = 4πr² = 4 * π * 8 ² = 256π inches ²

Therefore the correct answer is second option 256 π in²

Answer 2

256 π cu in

Explanation:

We have a regular sphere with a radius of 8 inches.

The surface area of such sphere is given by the formula:

A = 4 * π * r²

So, in our case, we have:

A = 4 * π * 8² = 4 * 64 * π = 256 π cubic inches.

We'll stop the calculation there since it was looking for an answer expressed with π.

I hope that helps you.
