Question : The radius of a sphere is 14 cm. What is the surface area of this sphere? [Use $\pi=\frac{22}{7}$]
Option 1: 2464 cm2
Option 2: 1232 cm2
Option 3: 1848 cm2
Option 4: 616 cm2
Correct Answer: 2464 cm 2
Solution :
Given: Radius, $r$ = 14 cm
The total surface area of a sphere
$= 4\pi r^{2}$
$=4\pi (14)^{2}$
$=4\times \frac{22}{7}\times 196$
$=2464$ cm
