the radius of a circle is 8 miles. what is the circles area? round your answer to the nearest hundredth. square miles
Answer
Explanation:
Step1: Write the formula for the area of a circle
The formula for the area of a circle is (A=\pi r^{2}), where (r) is the radius of the circle.
Step2: Substitute the value of the radius into the formula
Given (r = 8) miles. Substitute (r=8) into (A=\pi r^{2}), we get (A=\pi\times(8)^{2}).
Step3: Calculate the value
First, (8^{2}=64). Then (A = 64\pi). Using (\pi\approx3.1415926), (A=64\times3.1415926 = 201.0619)
Answer:
(201.06)
