Question

An ice cream vendor puts a hemispherical scoop of ice cream on a cone which has radius 7 cm and height 15 cm. Find the volume of ice cream put on the cone.

• A. $700c{m}^3$
• B. $733.33c{m}^3$
• C. $718.66c{m}^3$
• D. $702.05c{m}^3$

Answer 1

The correct option is C

$718.66c{m}^3$

The volume of ice cream is equal to the volume of the hemispherical scoop and the radius of the scoop will be equal to the radius of the cone.
Given, radius of the cone, r = 7 cm

$\text{Vol. of ice cream}=\frac{2}{3}\pi r^3=\frac{2}{3}\times \frac{22}{7}\times 7^3=718.66c{m}^3$
