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}

Options:

A . 3.5 cm

B . 10.5 cm

C . 14 cm

D . None of these

Answer: Option C
:
C
Ans: c.

Soln: Volume of a cylinder = πr

^{2}

h
Area of the base = π r

^{2}

Thus, height =

(\frac{V o l}{S u r f a c e A r e a}) = \frac{511}{36.5}

= 14.
