The circumference of a circle is 5pie m. Find it’s diameter.

The diameter is: d = 5m

Step-by-step explanation:

We know that

Circumference of Circle = 2πr

Given that

The circumference of a circle = 5π

so the equation becomes

Circumference of Circle = 2πr

                                 5π  = 2πr

                                 2πr = 5π

                                      r = 5π/2π

                                      r = 5/2 m

As we know that:

The diameter is twice the radius. i.e. d = 2r

Thus, the diameter is:

d = 2(5/2)

  = 5 m

Therefore, the diameter is: d = 5m

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
