Question

The volume of a cylinder is 210 cm³ with a radius of 14 cm find the curved surface area if the formula for curved surface area is

2πrh​

Answer 1

30 cm²

Explanation:

we need to find h

V=πr²h

h=V/πr²

h=210/14²π

h=0.341

then we found curved surface area

A=2πrh

A=2×π×14×0.341

curved surface are= 30 cm²
