Question

Find the height of the right cylinder whose volume is 511 cm${}^3$ and the area of the base is 36.5 cm${}^2$.

• A. 3.5 cm
• B. 10.5 cm
• C. 14 cm
• D. None of these

Answer 1

The correct option is C 14 cm

Ans: c.

Soln: Volume of a cylinder = πr${}^2$h

Area of the base = π r${}^2$

Thus, height = $\left(\frac{Vol}{SurfaceArea}\right)=\frac{511}{36.5}$= 14.
