Question

if radius of sphere is 2r find its volume. plz show long term method.

Answer 1

radius of the sphere(R) = 2r. volume of the sphere= 4/3πR^3 cube unit. 4/3π(2r)^3. 32r^3π/3 cube unit

Answer 2

given radius of the sphere =2r
volume of the sphere = 4/3*pi* (radius)^3

=4/3*22/7*(2r)^3
=4/3*22/7*2r*2r*2r
=(4*22*2*2*2*r*r*r)/(7*3)
=(704/21)r^3 cubic units
