To find the circumference of a circle you have to multiple the radius by 2 and also by pi. So, to find the radius when given just the circumference, who have to do the reverse operation and divide the circumference by 2 and also by pi to get the answer of 22.92993631, which you could of course round.

Answer:
$1.25
Step-by-step explanation:
90 / 72 = the cost per student
90 / 72 = 1.25
4y - y + 7y
4y - y = 3y
3y + 7y = 10y
10y is your answer
hope this helps
(t^2+1)^100
USE CHAIN RULE
Outside first (using power rule)
100*(t^2+1)^99 * derivative of the inside
100(t^2+1)^99 * d(t^2+1)
100(t^2+1)^99 * 2t
200t(t^2+1)^99
