Question

the c.s.a of righta circular cylinder is radius 2cm and area is 264cm find height of the cylinder. ​

Answer 1

† Question †

Given

Radius=2cm

Area =264 cm

height=?

$\rule{300}2$

◇ Solution ◇

$C.S.A=2πrh\\ = 264=2×\frac{22}{7}×2×h\\h=\frac{264×7}{2×22×2}\\h=21cm$

$\rule{300}2$

Hence,

height=21cm
