Hello there!
First, let's take a look at what the formula for the circumference and area of a circle is.
The circumference is "2
r", or "2 * 3.14 * r".
The area is "r^2", or "3.14 * r * r".
Let's establish what the radius is, as is equivalent to 3.14.
The radius is half of the diameter, and our diameter is 10.
Divide 10 by 2 to find our radius.
10 / 2 = 5
The radius is 5.
Now, let's plug in 5 for the radius for both formulas.
C = 2 * 3.14 * 5
10 * 3.14
31.4 is our Circumference.
Now, onto the area.
A = r * r * 3.14
5 * 5 * 3.14
25 * 3.14
78.5 is our Area.
I hope this helps!
