Question

Curved surface area of a right circular cylinder is 4.4 m2

.If the radius of the base of the cylinder is 0.7 m, find

its height.​

Answer 1

Answer:

⇒R=0.7m

⇒CSA=4.4 m

2

Let's assume height be x

⇒2πrh=4.4 m

2

⇒2×

7

22

×0.7x=4.4

⇒x=

2×22×0.7

4.4×7

=1m

⇒Height =1m

Answer 2

Let the height of circular cylinder be h.

Radius (r) of the base of cylinder =0.7m

Curved Surface Area of Cylinder =2πrh

4.4m² = 2πrh

4.4m² = (2×22/7×0.7×h) m

44/10m = (2×22/7 × 7/10×h)

44m = (2×22×h)

H = 44/2×22

H = 1m

Therefore the height of the cylinder 1m
