I need help ASAP I’ll give brainleist “air is leaking from a spherical shaped advertising balloon at a rate of 26 cubic feet per minute. If the balloon has a radius of 7 feet, how long will I take to fully empty? Use 3.14 for pi. Round your answer to the nearest minute”

Explanation:

If the radius is r = 7, then the volume of the sphere is approximately...

V = (4/3)*pi*r^3

V = (4/3)*3.14*7^3

V = 1436.02667 cubic feet approximately

The air is escaping at a rate of 26 cubic feet per minute. After x minutes, the balloon loses 26x cubic feet of air.

If we start with roughly 1436.02667 cubic feet of air, and lose 26x cubic feet of air after x minutes, then we have 1436.02667-26x cubic feet of air leftover. Set this equal to 0 to find out when the balloon will run out of air.

1436.02667-26x = 0

1436.02667 = 26x

26x = 1436.02667

x = 1436.02667/26

x = 55.231795

Rounded to the nearest minute, we get roughly 55 minutes.

Side note: to get a more accurate answer, you'll need to use a more accurate version of pi.

the answer is 375 miles
