Use the correct formula to find the area of the circle of the error to is 21 mi round to the nearest hundreds place use 3.14 for x a $346.19 mi 2 B 65.94 MI 2 c 13188 mi 2d 1,384.74 mi 2
The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the error is 21 mi, the radius of the circle is half of that, so r = 21/2 = 10.5 mi.
Substitute r = 10.5 mi and π = 3.14 into the formula:
A = 3.14 * (10.5)^2
A = 3.14 * 110.25
A = 346.185
Rounded to the nearest hundredth place, the area of the circle is 346.19 mi^2.
Therefore, the answer is A) $346.19 mi^2.
