Question

How many $c{m}^3$ of milk can a hemispherical bowl of diameter 10.5 cm hold?
$[Assume\pi =\frac{22}{7}]$

Note : Hemisphere is half a sphere.

• A. $301.1875c{m}^3$
• B. $302.1875c{m}^3$
• C. $303.1875c{m}^3$
• D. $304.1875c{m}^3$

Answer 1

The correct option is C

$303.1875c{m}^3$

Radius (r) of the hemispherical bowl $=\left(\frac{10.5}{2}\right)cm=5.25cm$
Volume of the hemispherical bowl $=\frac{2}{3}\pi r^3$ (half of the volume of a sphere)
$=[\frac{2}{3}\times \frac{22}{7}\times (5.25{)}^3]c{m}^3$
$=303.1875c{m}^3$
