Answer:
The diameter is 14π
Step-by-step explanation:
We know the area of a circle is πr^2
let 49π=πr^2
Cancel the π's, and you get 49=r^2
Take the square root and you get r=7
The diameter of a circle is 2πr.
2π(7)=14π.

360 people in 3 hours. 120 people per hour.
Step-by-step explanation:
How many times do 20 minutes go into 3 hours?
Well, 60 min. ÷ 20 min. = 3
So, 3 x 3 = 9
So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.
So 3 hours would be 9 x 40 = 360
120 people per hour because 40 x 3 = 120
and 20 minutes (3) times equals 1 hour.
