If the diameter is 3 feet, then the radius is 1.5 feet. Area of a circle = pi * radius squared or 
A = pi * (1.5)²
A = pi * 2.25
A = 3.14 * 2.25
A = 7.065 ≈ 7.1
7.1 feet² is your answer.
A = pi * (1.5)²
A = pi * 2.25
A = 3.14 * 2.25
A = 7.065 ≈ 7.1
7.1 feet² is your answer.
You are solving for the area of circular shape.
Let area = A
Let π= 3.14
Let radius = 1.5
The formula is as followed, you fill in the blanks:
The answer exact answer is 7.07, but if you were to round it, because you want an approximate answer it would be 7.1 square feet.
<span>Your answer from your choices given is bolded, and the work is in the picture:
- 7.1 square feet
- 9.4 square feet
- 18.8 square feet
- 28.3 square feet

Answer:
- The amount invested at 5%=$77,000
- The amount invested at 9%=$349,000
Step-by-step explanation:
- Let the amount invested at 5% simple interest =$x
He invested $41,000 more than 4 times the amount at 9%.
- This amount is: $(4x+41000)
Total Annual Interest Earned = $35,260
Therefore, Time=1 year
Simple Interest
Therefore, his total interest
=Interest from Investment 1 + Interest from Investment 2
Therefore:
The amount invested at 5%=$77,000
The amount invested at 9%=$(4*77,000+41000)=$349,000
