Question

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

Answer 1

380.13 m

Explanation:

You first need to write down the Area formula for a circle which is A=pi x radius^2 .

So 11^2 x 3.1415...

121 x 3.1415... = 380.13 m
