Question

curved surface area of a right circular cylinder is 8.8m². if the radius of the base of the cylinder 1.4m. Find its height.

​

Answer 1

Answer:

1 metre

Step-by-step explanation:

Given:-

CSA of Cylinder = 8.8m²

Radius of base of Cylinder ,r = 1.4 m

To Find:-

Height of Cylinder ,h

Solution:-

we have to calculate the height of the cylinder. As we know that the formula to calculate the Curved Surface Area of Cylinder.

• CSA of Cylinder = 2πrh

where,

π denotes 22/7

r denotes radius

h denotes height

Substitute the value we get

→ 8.8 = 2×22/7 × 1.4 × h

→ 8.8 = 44/7 × 1.4 × h

→ 8.8 = 8.8 × h

→ h = 8.8/8.8

→ h = 1 m

Hence, the height of the Cylinder is 1 metre.
