Question

Find the volume of surface area of a sphere with radius 5cm .

Answer 1

volume= 4/3πr^3

4/3* 22/7*5*5*5

11000/21=523.8cm3

S.A= 4 *22/7*5*5

=314.2cm2

Answer 2

The volume of sphere is $\dfrac{500}{3}\pi\ cm^3$

The surface area of sphere is $100\pi\ cm^2$

Step-by-step explanation:

Radius of sphere, r = 5 cm

Volume of sphere $=\dfrac{4}{3}\pi r^3$

Volume of sphere $=\dfrac{4}{3}\pi 5^3$

Volume of sphere $=\dfrac{500}{3}\pi\ cm^3$

Surface area of sphere $=4\pi r^2$

Surface area of sphere $=4\pi 5^2$

Surface area of sphere $=100\pi\ cm^2$
