Question

The Volume of hemisphere is 155232 cm³.What is the radius of the hemisphere?

• A. 70 cm
• B. 42 cm
• C. 38 cm
• D. 40 cm

Answer 1

Answer:

B. 42 cm

$Volume = 155232 cm^3$

Volume of hemisphere $=\frac{2}{3}\pi{r^3}$

=>\frac{2}{3}\pi{r^3}=155232

=>\frac{2}{3}\times{\frac{22}{7}}\times{r^3}=155232

=>r^3=74088

$r=42cm$
