The circumference of a circle is 20m. What is the area, in square meters?
1 answer:
Answer:
c = 62.83185
a = 314.15927 m²
Step-by-step explanation:
Hey There!
So first thing that we want to do is find the formula for the circumference

where r = radius
we are given the diameter which we can easily convert to radius by dividing by 2
20/2=10
so the radius is 10
now we plug in

So the circumference is equal to 62.83185 m ²
Now to find the area we use the formula


so we can conclude that the area of the circle is 314.15927
