Question

If the diameter of a sphere is 16 cm, then its surface area is: 

​

Answer 1

Answer:

804.57 cm²

Step-by-step explanation:

GIVEN :

Diameter of a sphere =  16 cm

⇒Radius of the sphere = 16 ÷ 2

                                      = 8cm

To Find:

The Surface Area  of the  sphere

Formula:

$\boxed{The .Surface .Area .of. the .sphere = 4\pi r^{2} }$ where r is the radius

Solution:

The Surface Area  of the  sphere = 4πr²

                                                       = 4 × $\frac{22}{7}$ × 8 × 8

                                                       =$\frac{5632}{7}$

                                                       =804.57 cm²
