Question

5. The curved surface area of a cylinder is 100π m2. Length of the cylinder is 10 m. Find its Radius?
​

Answer 1

Step-by-step explanation:

Given that, the lateral surface area of a cylinder of height 10 cm is 100 cm

2

.

To find out: The radius of the base of the cylinder.

We know that, lateral surface area of a cylinder is 2πrh

∴ 2πrh=100

⇒2πr(10)=100

⇒20πr=100

⇒r=

20π

100

∴ r=

π

5

Hence, the radius of the base of the given cylinder is

π
