Answer 2

The surface area of the sphere is 1810.28 cm².

Given,

The radius of the sphere is 12 cm.

To Find,

The surface area of the sphere.

Solution,

The formula for calculating the surface area of the sphere is

The surface area of the sphere = 4πr²

where,

r is the radius of the sphere

π is a constant whose value is 22/7.

Now,

Surface area = 4*22/7*12*12

Surface area = 12672/7 = 1810.28 cm²

Hence, the surface area of the sphere is 1810.28 cm².
