Question

add at the park there's a pool shaped like a circle with a diameter 22 yards. A ring shaped path goes around the pool. it's width is 5 yards.

Answer 1

135pi

Explanation:

(I'm guessing you want to know the ring's area)

Diameter = 22 yards, meaning Radius = 11 yards

`(11+5)^(2)\pi` = 256pi = Outer Ring + Pool

`(11)^(2)\pi` = 121pi = Pool

Outer Ring = 256pi - 121pi = 135pi

Answer 2

424 yards²

Explanation:

Diameter 22, radius 11

Outer circle: radius = 11+5 = 16

Area of the path:

Pi× (16²-11²)

= 135pi yards²

Or, 424 yards² (3 sf)
