# Find the Surface Area of a Sphere of Radius 7 Cm. - Geometry

Sum

Find the surface area of a sphere of radius 7 cm.

#### Solution

Radius of the sphere, r = 7 cm

∴ Surface area of the sphere, S =  $4\pi r^2 = 4 \times \frac{22}{7} \times \left( 7 \right)^2$  = 616 cm2

Thus, the surface area of sphere is 616 cm2.
