Question

curved surface area of a right circular cylinder of height 14 cm is 88 cm2. The diameter

of the base is ……………
​

Answer 1

Given , The height of cylinder =14cm

and , the curved surface area of cylinder =88cm

2

we know that ,

the curved surface area of cylinder =2πrh

and 2r=d

here , r=radius of cylinder , d=diameter of cylinder and h=height of cylinder

so , the curved surface area of cylinder =πdh =88cm

2

π×d×14=88

×d×14=88

d=2cm

Answer 2

Answer:

The curved surface area of a right circular cylinder of height 14 cm is 88 cm2 . Find the diameter of the base of the cylinder. Let the radius of the base of the cylinder be r cm. Hence, the diameter of the base of the cylinder is 2 cm.
