Answer:
D) 5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%

Area of the circle is 78.5 sq. units.
<u>Step-by-step explanation:</u>
Circumference of the circle = 31.4 units
2 π r = 31.4 units
2 × 3.14 ×r = 31. 4 units
r = 31.4 / (2×3.14)
= 5 units.
Area of the circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.
