Question

the curved surface area of a cylinder with height of 8cm is 176 cm square. find its radius of base.
pls answer​

Answer 1

Answer:

2*pi*r*h = 176 cm2

2*(22/7)*r*8 = 176

r = 3.5 cm

Answer 2

Radius of base is 3.5 cm.

Given:

The curved surface area of a cylinder with height of 8cm is 176 cm square.

To find:

Find its radius of base.

Solution:

We have the formula of curved surface area of cylinder as 2πrh

Here, r is radius and h is height

We have been given height as 8 and curved surface area as 176

We just have to put values into formula

2πrh = 176

2 * 22/7 * r * 8 = 176

16 * 22/7 * r = 176

22/7 * r = 176/16

22/7 * r = 11

22r = 11*7

r = 77/22

r = 3.5

Hence, radius of base is 3.5 cm.
