Question

The area of the base of a right circular cylinder is $154c{m}^2$ and its height is $15cm$. Find the volume of the cylinder.

• A. $2310{cm}^3$
• B. $2010{cm}^3$
• C. $1850{cm}^3$
• D. $1310{cm}^3$

Answer 1

The correct option is A $2310{cm}^3$

Let the radius of the base of cylinder be 'r' cm.
now, area of the base of cylinder$=154c{m}^{2}or=154c{m}^2{r}^2=\frac{154\times 7}{22}=49r=\sqrt{49}=7cm$
volume of cylinder$=\pi r^{2}h=\frac{22}{7}\times 7\times 7\times 15=2310c{m}^3$
