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! (:

Does this table represent a function? Why or why not? <br><br> Pick A,B,C or D

stepladder [879]

The answer would be D.

In order for a table to represent a function, each x-value needs to pair with exactly one y-value and no more.

In the table shown here, none of the x-values repeat and all of them pair with a unique y-value which means that it’s a function.

The formula for the distance travelled over time t and at an average speed v is v⋅t. Amit ran for 40 minutes at a speed of about

lawyer [7]

Answer:

3 1/3 km or 3.33 km (to the hundredth)

Step-by-step explanation:

Using the given formula,

estimated distance = v.t = velocity * time,

velocity = 5 km/h

time = 40 minutes = $\frac{40}{60}$ hours = $\frac{2}{3}$ hours
