Question

Find the volume and surface area of a sphere with radius 3 centimeters. Round your answer to two

Answer 1

The Volume of the sphere with radius 3 cm is 113.10 cm³  and the surface area is  113.10 cm² .

In the question ,

it is given that ,

the radius of the sphere is = 3 cm

we know that formula for Volume of sphere is

Volume = (4/3)πr³

So , Volume for radius = 3 cm is

Volume = (4/3)π(3)³

= (4/3)*3.14*27

= 113.097

≈ 113.10 cm³

And the formula for the Surface area is given as

Surface Area  = 4πr²

Surface area for  radius = 3 cm is

Surface Area = 4*3.14*9

= 113.097

≈ 113.10 cm²

Therefore , The Volume of the sphere with radius 3 cm is 113.10 cm³  and the surface area is  113.10 cm² .
