Question

Find the volume of a sphere whose r is 20 inches?

Answer 1

33493.34

Explanation:

r=20

volume of sphere= 4/3×πr^3

= 4/3×3.14×20^3

= 33493.34

or

r=20

volume of sphere= 4/3×πr^3

= 4/3×22/7×20^3

= 33523.80952

Answer 2

`\boxed{\boxed{\pink{\bf \leadsto The \ Volume \ of \ the\ sphere\ is\ 33493.33 \ in.^3 }}}`

Explanation:

According to the Question the radius of the sphere is 20 inches. And we know that the Volume of sphere is given by :-

`\boxed{\orange{\sf Volume_(sphere)=(4)/(3)\pi r^3 }}`

And here radius is 20 in.

`\implies Volume = (4)/(3)\pi r^3 \\\\\implies Volume =(4)/(3)*(22)/(7)* (20 in.)^3\\\\\implies \boxed{\bf Volume = 33493.33 in^3 }`

Hence the Volume of the sphere is 33493.33 inch³.
