Question

In the total area of solid sphere is 98.56cm^2, then find the radius of the sphere

Answer 1

The Area of sphere is 4πr^2 and the area is given already. You have to do is to assume radius as r and Follow the steps provided in pic ↑↑↑ and

Answer 2

let radius of the sphere = r cm
total surface area of the sphere = 98.56cm²

4πr² = 9856/100
4* 22/7 *r² = 9856/100
r² = (9856*7)/(100*4*22)
after cancellation

r² =(28 * 28 )/(10*10)
r² = (28/10)²
r = 28/10
r= 2.8 cm
