First we have to find the diameter of the circle. The diameter is a straight line that passes through the circle. Since we know the radius is 11 m, we can multiply that by 2 to get the diameter.
Diameter- 22 m
Now we multiply the diameter by Pi (3.14) and we get 69.08 m
We would round 69.08 to 69, or to be less specific, 70.
I hope this helped! Please correct me if I’m wrong.
First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.
