Question

what is the best estimate for the area of circle a, in square units? use the approximation π ≈ 3.14.
a) 2198 square units
b) 43.96 square units
c) 113.04 square units
d) 153.86 square units

Explanation:

Step1: Determine the radius of the circle

From the graph, the radius \(r = 6\) units.

Step2: Use the formula for the area of a circle

The formula for the area of a circle is \(A=\pi r^{2}\). Substitute \(r = 6\) and \(\pi\approx3.14\) into the formula:
