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

Answer:

424 yards²

Step-by-step 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)

Answer 2

Answer:

135pi

Step-by-step 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
