Question

A right circular cylinder has its diameter R cm and height as R/2 cm. Prove that its volume is pie r cube upon 2cube​

Answer 1

Step-by-step explanation:

so Diameter is = R cm

then radius = R/2 cm

now height is also = R/2 cm

so volume of cylinder =

22/7 × r^2 × h

22/7x (R/2)^2 × (R/2)

so according to that

vol = 22/7 ×(R/2)^3

22/7 × R^3 / (2)^3

now according to question we were supposed to prove that pie×r^3/(2^3) = volume of cylinder

Hence proved
