# Find the Surface Area and Volume of Sphere of the Following Radii. - Geometry

Sum

Find the surface area and volume of sphere of the following radii.

3.5 cm

#### Solution

Radius of the sphere, r = 3.5 cm
Surface area of the sphere =  4 πr2 = 4 × 3.14 × (3.5 cm)2 = 153.86 cm2

Volume of the sphere = 4/3πr3 = 4/3 x 3.14 x (3.5 cm)3 = 179.50 cm3

Is there an error in this question or solution?
