Answer:
314.159265359 ft squared or 314.16 ft squared rounded to the hundredths place. The closest result is option C.
Step-by-step explanation:
The formula for finding the area of a circle is A=π×r^2.
Step 1: Find the radius which is half of the diameter. In this case, the radius is 10 feet.
Step 2: Square the radius that you found. In this case, the number will be 100ft or 10^2.
Step 3: Multiple this number by π, or 3.14 if your teacher allows it. So in this case, 100×π=314.159265359 or 314.16 rounded to the hundredths place. If you use 3.14... the answer is 314.
Step 4: You've got your answer. Hope this helps!
