Question

The spray from a sprinkler reaches 21 feet from the sprinkler and creates a circle as it spins. what is the circumference of the circle sprayed by the sprinkler? use 227 for π.

Answer 1

The answer like he said is 131.9 but round it to the nearest tenth will be 132 ^^

Explanation:

Answer 2

The formula for circumference is C = 2πr.

We already know that the radius of the circle is 21 feet, so let's plug that into the equation.
C = 2π(21)
Now let's simplify
C = 6.28(21)
C = 131.9

131.9 is your circumference.
