A cone has volume 817. What is the volume
of a cylinder with the same radius and height?

The volume is 416

volume of cylinder =π r^2 h

Step-by-step explanation:

Volume is proportional to square of radius and linearly proportional to height of cylinder. if h kept constant radius is doubled volume increases by 2^2 ie it becomes 4 fold. If radius trebled volume will be 9 times the original keeping h constant

if you keep h constant increase radius 4 times volume increases by 4 times only

v/πr^2h is constant =π like circumference/diameter =π

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

ratio is 2 : 9

the answer is three

13.5 : 3
