Question

What is the volume of hemisphere bowl if its radius is $21m$?

• A. $19404m^2$
• B. $1904m^2$
• C. $19303m^2$
• D. $19505m^2$

Answer 1

The correct option is A $19404m^2$

Given the radius $\left(r\right)$ of the hemispherical bowl is $21$ m.

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

Then the volume of the bowl will be $\frac{2}{3}\times \frac{22}{7}\times (21{)}^3=44\times 21\times 21$

Volume of the bowl $=19404$ cm${}^3$.
