The equation for circumference is 2piR. Because your diameter is 22, your radius is 11. 2 x pi = 6.28. 6.28 x 11 = 69.08. So letter D is your answer.

blondinia [14]

Answer:

<em>Habiba will pay $262.20 of Interest.</em>

Step-by-step explanation:

<u>Simple Interest</u>

Simple interest is a method of calculating the interest charge on a loan. The Interest (I) is determined by multiplying the yearly interest rate (r) by the principal (P) by the number of years that elapsed between payments (t).

The formula to calculate the interest Habiba will pay is:

I=P.r.t

The values are:

P=950

t=3 years

r=9.2% yearly= 0.092

Substituting the values:

I=950*0.092*3

I=262.20

Habiba will pay $262.20 of Interest.
