Question

The volume of the cylinder is 225(pi) cm³. What is the height of
the cylinder?
(A) 6.25 cm
(B) 25 cm
(C) 37.5 cm
(D) 75 cm
​

Answer 1

Answer:

it's 25 cm

Step-by-step explanation:

Volume = 225π

or πr²h= 225π

or r²h= 225

or h= 225/r²

here diameter d = 6cm so radius r=d/2 = 3cm

or h= 225/3²

hence h= 25cm
