Question

what is the best estimate for the area of circle a, in square units? use the approximation $piapprox3.14$.

Explanation:

Step1: Determine radius r

From grid, center A to point B is 6 units (r=6).

Step2: Calculate area

Area formula: $A = \pi r^2$. Substitute $r=6$, $\pi\approx3.14$: $A = 3.14\times6^2 = 3.14\times36 = 113.04$.

Answer:

C) 113.04 square units
