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.

Given, Curved surface area = 88 cm²

h = 14 cm

∴ 2πrh = 88

2πr x 14 = 88

r = $\frac{88}{28\mathrm{\pi }}$

r = $\frac{88}{28}\times \frac{7}{22}$ = 1 cm

Now, diameter = 2r = 2 x 1 = 2 cm
