Answer:
100π square inches
Step-by-step explanation:
The area of a circle is given by ...
A = πr^2
where r is the radius. The radius of a circle is half the diameter, so your circle with 20 inch diameter has a radius of 10 inches. Putting that value into the formula gives an area of ...
A = π·(10 in)^2 = 100π in^2
The area is 100π square inches.
The unknown is the interest rate.
The givens are the principal=$4800, time=8.5 years and amount=$8000(to find the interest, subtract the principal from the amount,$8000-$4800=$3200)so interest is $3200
The formula for finding rate is R=I*100/PT where R is rate, I is interest and P is principal and T is time.the 100 is there because R is a percentage.
R=$3200*100/$4800*8.5=7.8%(rounded to nearest tenth)
Therefore the interest rate is about 7.8%
