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! (:

Answer:

b = -27

Step-by-step explanation:

-1/3 b = 9

Multiply each side by -3

-3 * -1/3 b = -3 * 9

b = -27
