So to do this one, you have to do the problem backwards!
The equation looks like this with everything plugged in:
272.2 = 2(3.14)r
You are looking for r, so start dividing
272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r
Therefore the radius is about 43.3 in.
I hope I helped!
<h3>T
he monthly payment is $242.44 for loan to paid off in 3 years.</h3>
Step-by-step explanation:
The amount borrowed = Principal = $8000
The rate of interest = 7.2%
Time (T) = 3 years

So, the total interest = $1728
Now, <u>Amount to be paid = Principal + Interest</u>
⇒ A = $8000 + $1728 = $8728
Also, 1 year = 12 months
⇒ 3 years = 3 x 12 months = 36 months
So, total amount to be paid in 36 months is $8728.
⇒The amount to be paid in 1 month is 
Hence, the monthly payment is $242.44 if loan is to paid off in 3 years.
