Asked in: July 2024 board paper

A cylinder is having radius 7 cm and height 21 cm. Complete the following activity to calculate its volume and circumference of its base.

Activity: Radius (r) = 7 cm, Height (h) = 21 cm

Volume of cylinder = ____ (Formula) \(= \dfrac{22}{7} \times 7 \times 7 \times \text{____} = 154 \times 21 = \text{____}\) cm\(^3\)

Circumference of base = ____ (Formula) \(= 2 \times \dfrac{22}{7} \times \text{____} = \text{____}\) cm

Best answer

Answer: Volume = 3234 cm\(^3\); circumference of base = 44 cm

Volume of cylinder \(= \pi r^2 h = \dfrac{22}{7} \times 7 \times 7 \times 21 = 154 \times 21 = 3234\) cm\(^3\).

Circumference of base \(= 2\pi r = 2 \times \dfrac{22}{7} \times 7 = 44\) cm.

Blanks: \(\pi r^2 h\); 21; 3234; \(2\pi r\); 7; 44.
