Question

15. A zoo is building a glass cylindrical tank

for the small sharks. The tank is 10 feet
high and has a diameter of 16 feet. How
much water is needed to fill the tank?
(The volume of a right circular cylinder is
V = Tr?h, where r is the radius, h is the
height, and a = 3.14.)

Answer 1

2,010.6192982

Explanation:

Answer 2

2009.6

Explanation:

As we know, volume of a right cylinder is πr²h.

here, diameter is mentioned, which gives that the radius is half of the diameter.

r= 1/2*16=8 feet

height= 10 feet

π=3.14

volume= 3.14*8²*10

= 3.14*64*10

=3.14*640

= 2009.6

so, that much water is needed to fill the tank
