Please help and explain questions 20-22

Hello!

The formula for circumference is 2\pi r and the formula for area of a circle is \pi r^{2}. Armed with these formulas, we can begin to find the circumferences and areas of the circles.

20. 
C = 2 \pi r
C = 2 \pi (6.5)
C = 13 \pi
C = 13(3.14)
C = 40.8

A = \pi r^{2}
A = \pi (6.5)^{2}
A = \pi (42.25)
A = 132.7

The circumference of the circle is 40.8 in and the area of the circle is 132.7 in².

21.
[Since we are given the diameter for this problem, to find the circumference, we no longer need to multiply the radius by 2 as in 2 \pi r because the diameter is the radius × 2. For \pi r^{2} we do need to divide the diameter by 2.]

C = 15.7 \pi
C = 49.3

A = \pi r^{2}
A = \pi (7.85)^{2}
A = 61.62 \pi
A = 193.5

The circumference of the circle is 49.3 in and the area of the circle is 193.5 in².

And that is all there is to it. I hope this helps you! (:
