Question

The diagram shows the edges of a resort swimming pool at water level. Note: Figure is not drawn to scale. If Ursula swims around the pool along its edge one time, approximately what distance will she have gone? A. 35.87 feet B. 71.74 feet C. 40.97 feet D. 47.74 feet

Answer 1

The total distance covered by Ursula will be 47.74 feet.

What is the distance?

Distance is defined as the length between the two points just like in the question it is the length between the school and the park.

The distance covered by Ursula will be calculated as follows:-

Arc1 = $140\times \dfrac{\pi}{180}\times (4)$

Arc1 = 2.51  x  4  =  10.04 feet

Arc2 = $106\times \dfrac{\pi}{180}\times (4)$

Arc2 = 1.85  x  4  = 7.4 feet

Arc3 = $90\times \dfrac{\pi}{180}\times (4)$

Arc3 = 1.57  x  4  =  6.28 feet

Other lengths from the given figure are 6,8 and 10 feet.

The total distance will be:-

= 10.04 + 7.4 + 6.28 + 6 + 8 + 10

= 47.74 feet

Therefore the total distance covered by Ursula will be 47.74 feet.
