Question

Find the height of the right circular cylinder if its curved surface area is 176 sq. cm and radius of the base is 4 cm. ​

Answer 1

Answer:

Given:

CSA= 176 sq. cm

radius= 4cm

CSA= 2πrh

176= 2*22/7*4*h

176*7= 44*4*h

1232=176*h

h= 1232/176

h= 7cm

Therefore, the height of the right circular cylinder is 7cm.

Answer 2

Answer:

7

Step-by-step explanation:

We know that the curved surface area of a right circular cylinder with radius r and height h is CSA=2πrh.

It is given that the height is CSA=176 sq and the radius is 4 cm, therefore,

CSA=2πrh

176=2 x 22/7 x 4 x h

176 x 7 =2x22x4xh

1232 = 176xh

1232/176 = h

7cm=h

Hence, the height is 7cm
