Since rectangular piece of paper of rolled along its length.
∴ 2πr = 22
r = 22 × 7 / 2 × 22 = 3.5 cm
Height of cyclinder (h) = 10 cm
∴ Volume of cyclinder = πr2h
= 22 / 7 × 3.5 × 3.5 × 10
= 385 cm3.
∴ 2πr = 22
r = 22 × 7 / 2 × 22 = 3.5 cm
Height of cyclinder (h) = 10 cm
∴ Volume of cyclinder = πr2h
= 22 / 7 × 3.5 × 3.5 × 10
= 385 cm3.
