MATH HELP.? EXTRA 5 POINT AND BEST ANSWER.

[From: ] [author: ] [Date: 11-12-14] [Hit: ]
Circumference is 62.86 feet.That means there are either 20 or 21 parents.20 pi divided by 3 = approximately 21 sets of parents-first, find the diameter.that is 20*pi which is approximately 63.......
Here is the question,
At the park is a circular wading pool 20 ft in diameter. If parents are seated on the edge of the pool about every 3 ft, how many parents are sitting on the edge of the pool?

-
You need to find the circumference of the pool. The equation for that is 2*pi*radius.

Radius is half of diameter, so it's 10 ft.

2*pi*10ft

We'll just say that pi is 22/7 for simplicities sake.

2*(22/7)*10ft

Circumference is 62.86 feet. (Roughly)

That means there are either 20 or 21 parents. (More 21 than 20)

-
Circumference of pool = pi * diameter = 20pi ft
20 pi divided by 3 = approximately 21 sets of parents

-
first, find the diameter.
that is 20*pi which is approximately 63.
divide by 3 to get 21 as your answer
