Q:

Part A:At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle (blue) with a radius of 11 m. The inner edge of the sidewalk is a circle (orange) with a radius of 9 m. Find the approximate AREA of the larger circle (blue). Use 3.14 for pi.Show your work!Part B:At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle (blue) with a radius of 11 m.

A:
Answer:Part A: 379.94Part B: 254.34Part C: 125.6Step-by-step explanation:The are for the area of a circle is A = Pi*r^2So for part A, do A = 3.14 * 11^2A = 3.14 * 121A = 379.94Same thing for Part B, just change the radius:A = 3.14 * 9^2A = 3.14 *81A= 125.6And for Part C, Subtract the area of the smaller from the area of the larger circle:379.97 - 254.34 = 125.6
