Question

The dimensions of a conical funnel are shown below:

A conical funnel is shown with the height of the cone as 7 inches and the radius of the base as 3 inches.

Betty closes the nozzle of the funnel and fills it completely with a liquid. She then opens the nozzle. If the liquid drips at the rate of 14 cubic inches per minute, how long will it take for all the liquid in the funnel to pass through the nozzle? (Use π = 3.14.)

4.71 minutes

3.14 minutes

14.13 minutes

9.42 minutes

Answer 2

a i think

Answer 3

@heavenfun13 how ?

Answer 4

Answer 5

Volume of right circular cone is given by the formula:

V = (1/3) * pi * r^2 * h where r is the radius of the circular base and h is the height of the cone.

Answer 6

gaby?

Answer 7

@Reaper534 im lagging sorry....

Answer 8

ok so

v = 1/3 * 3.14 * 3^2 * 7

Answer 9

v = 65.94

Answer 10

yeah im lagging to now

Answer 11

@Reaper534 .-. lol

Answer 12

is it A ? i got A..

Answer 13

If 65.94 cubic units is the volume of the cone (I got 65.973 using more digits of pi), then ivide 65.973 cubic units by 14 cubic units per minute to see how many minutes it takes for the funnel to empty.

Answer 14

4.7 yes

Answer 15

thank you
