Q.3 (A)(2) 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)
\(= \dfrac{22}{7} \times 7 \times 7 \times\) ____
\(= 154 \times 21\)
\(=\) ____ cm3
Circumference of base = ____ ........ (Formula)
\(= 2 \times \dfrac{22}{7} \times\) ____
\(=\) ____ cm
