Question

curved surface area of a right circular cylinder is 4.4 m^ .If the radius of the base of the cylinder is 0.7 m , find itsbheight

Answer 1

Answer:

1 m

Step-by-step explanation:

Given, Radius = 0.7 m.

Given, Curved surface area = 4.4 m².

⇒ 2πrh = 4.4

⇒ 2 * 22/7 * 0.7 * h = 4.4

⇒ 2 * 22 * 0.1 * h = 4.4

⇒ 4.4 * h = 4.4

⇒ h = 1 m.

Therefore, height of cylinder (h) = 1 m.

Hope it helps!

Answer 2

CSA of cylinder=4.4m^2
Radius=0.7m
Height=?
CSA of cylinder=2πrh
4.4=2×22/7×0.7×h
4.4=44/7×0.7×h
h=1m
