Question

A 20 cm broad rectangular paper is folded along its length to make a cylinder with radius 7 cm . find the volume of the cylinder

Answer 1

Answer:

radius=7cm,height=20cm

volume=πr^2h=22x7^2 x 20/7

= 22x7x20 = 154x20 = 3080cm3

Answer 2

Answer:

V = 980

Step-by-step explanation:

Data :

Radius = 7 cm

Height = 20 cm

Required : Volume (V) = ?

SOLUTION :

V = π ×( r)^2 × h

= 7^(2)×20 × π

V = 980 π
