Question

Complete the following activity to find the volume of a cone if the radius of its base is 7 cm and its perpendicular height is 6 cm. 

Activity:

Here, radius (r) = 7 cm, height (4) = 6 cm

The volume of a cone = `square`      ...(Formula)

= `1/3 xx 22/7 xx square xx 6`

= `1/3 xx 22/7 xx square xx 6`

∴ the volume of the cone = `square` cm³.

Answer 1

Here, radius (r) = 7 cm, height (4) = 6 cm

The volume of a cone = \[\boxed{\frac{1}{3}πr^2h}\]

= \[\frac{1}{3} × \frac{22}{7} × \boxed{(7)^2} × 6\]

= \[\frac{1}{3} × \frac{22}{7} × \boxed{49} × 6\]

∴ the volume of the cone = \[\boxed{308}\] cm³.
