Question

Given radius of sphere is 7 cm, the surface area of the sphere is …. cm2
​

Answer 1

answer :

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

A = 4πr^2

where r is the radius of the sphere.

Substituting the given radius of 7 cm, we get:

A = 4π(7)^2

A = 4π(49)

A = 196π

Hence, the surface area of the sphere is 196π square centimeters. If you want a decimal approximation, you can use the approximation π ≈ 3.14 to get:

A ≈ 196(3.14)

A ≈ 615.44

So the surface area of the sphere is approximately 615.44 square centimeters.
