CATT. 2012​

Answer 1

Given,

Diameter of sphere = 56 cm

Then, Radius of sphere = 56/2  = 28 cm

To Find : Surface Area of Sphere

Surface area of sphere = 4πr²

                                      = 4π(28)² = 9847.04 cm²

Answer 2

Answer:

surface area of sphere=4πr²

diameter=56

then radius = 28

4×3.14×28²

=9,847.04
