Question

Please help me idk this

Answer 1

Answer: 10 is the radius of the circle

Step-by-step explanation:

62.8 divide by pi (3.14) = 20.

20 is the diameter.

In order to get the radius, we divide the diameter by 2, since a radius is half the diameter.

So, 20 divide by 2 = 10.

Answer 2

Answer:

The radius = 10 feet

Step-by-step explanation:

Its really simple. You have to find the radius of a circle if you know the circumference and π. You know the formula to find circumference:

C = 2πr

But we need to find the radius, so we rewrite the formula in a different way:

r = C / 2π

Now, we know that the circumference = 62.8 feet, and π = 3.14, so we can substitute:

r = 62.8 / 6.28 = 10 feet

And here is your answer!
