Question

curved surface area of right circular cylinder is 42 π cm² . If its height is 11 cm then find the radius of base of cylinder​

Answer 1

Solution:

Curved Surface Area of cylinder = 42π cm^2

Height = 11 cm

Radius of base of cylinder = ?

Curved Surface Area of cylinder = 42π cm^2

$2\pi rh = 42\pi \\ 2r(11) = 42 \\ r = \frac{42}{22} \\ r = \frac{21}{11}$

hope it helps you
