Question

The surface area of a solid sphere of radius 3 cm is ………… mm2​

Answer 1

Answer is very easy 11314.2 mm²

Answer 2

Given,

Radius of solid sphere=3cm

To Find,

Surface area of a solid sphere.

Solution,

Here  we have the value of radius of solid sphere as 3cm

For surface area we have to use the formula that,

Surface area=4πr²

                    =4×3.14×3²

                   =4×3.14×9

                   =113.142cm²

                  =11314.2mm²

Hence, the surface area of a solid sphere of radius 3 cm is 11314.2mm².
