Answer:
30.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
11 pi = 2 * pi *r
divide each side by 2 pi
11/2 = 2 ( pi) * r/ ( 2pi)
11/2 = r
We can find the area by
A = pi * r^2
= pi ( 11/2) ^2
= pi ( 121/4)
= pi ( 121/4)
= 30.25 pi
First, we plug in the numbers.
$40 = P(4%)(2)
4% = 0.04
40 = P * 0.04 * 2
Divide each side by 2
20 = P * 0.04
Divide by 0.04
P = 500
Lets check it!
500 * 0.04 * 2 = 40
500 * 0.04 = 20
20 * 2 = 40
40 = 40
