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.
Solution:
Let the radius and height of the cylinder be 'r' and 'h' respectively.
Curved Surface Area of a right circular cylinder = 2 π r h
Diameter = 2 × radius
Height of the cylinder, h = 14 cm
CSA of the cylinder = 88 cm²
2 π r h = 88 cm²
2 × 22/7 × r × 14 cm = 88 cm²
r = (88 cm² × 7) / (2 × 22 × 14) cm
= 1 cm
Diameter = 2 × radius
= 2 × 1 cm
= 2 cm
