Can someone help me please?

28pi, 10pi

Step-by-step explanation:

So, lets go over a few things.

What is circumference?

Circumference is the permiteter of a circle.

The formula for it is 2*r*pi.

Now, lets go over what radius and diamater is.

Diamater is the distance between the two opposite sides of the circle.

The radius is half of the diamater, and is the distance between one side of the circle and the middle.

Problem #1:

The distance from the middle to the side of the circle is 14.

This will be the radius, not the diamater.

Lets plug this into the formula:

2*14*pi

=

28*pi

=

28pi

This is your answer.

Problem #2

The distance from the two opposite sides of the circle is 10.

So the radius will be half of this, being 5.

Now lets plug this in:

2*5*pi

=

10*pi

=

10pi

This is your answer.

Hope this helps!
