Question

the radius of a sphere is 1 by 3r then find its volume

Answer 1

Answer:

Step-by-step explanation:

r=1/3r

Volume of sphere=?

Vol=4/3πr^3

=4/3π1/3^3

=4/3π1/27

Answer 2

The volume of sphere is $0.1552r^3$

Step-by-step explanation:

Radius of sphere =$\frac{1}{3}r$

Formula of volume of sphere =$\frac{4}{3} \pi r^3$

Substitute the value in the formula

Volume of sphere = $\frac{4}{3} \times \frac{22}{7} \times (\frac{1}{3}r)^3$

Volume of sphere =$0.1552r^3$

Hence The volume of sphere is $0.1552r^3$
