Answer:

d = 2r or d = C/π

Diameter is equal to two times the radius or Circumference/π

C = 2πr

Circumference is equal to two times π multiplied the radius

A = π * r²

The area of the circle equals to π multiplied by the radius squared

Step-by-step explanation:

Let's find the formulas for d, C and A

d = diameter

C = Circumference

A = Area

r = radius

π ≅ 3.1416

d = 2r or d = C/π

Diameter is equal to two times the radius or Circumference/π

C = 2πr

Circumference is equal to two times π multiplied the radius

A = π * r²

The area of the circle equals to π multiplied by the radius squared

Julie wrote the rate $108 in 6 weeks as a unit rate.Find her mistake and correct it.

natima [27]

Well for starters that would be $108/6 weeks when a unit rate is anything over one. To put it as a unit rate (how many dollars per hours) you just divide $108 by 6 (since you would divide 6 by 6 to get) and the unit rate would end up being $18 per hour.

To produce a box plot, we need the lowest and highest value from the data set. We also need the lower quartile ( $Q_{1}$ ), median ( $Q_{2}$ ), and upper quartile ( $Q_{3}$ ).

All these data and the box plot is shown in the diagram below

B is the midpoint of AC. If AB= X +5 and BC = 2X -11, find the measure of AB

Murljashka [212]

First, you know that B is the mid point, meaning AB is equal to BC. Therefore, you can set up the equation: x+5=2x-11. Then, you solve for x. Once you are done solving, you should get 16. Hope this helps!
