The formula for the circumference of a circle, c=πd or c=2πr, can also be used to find the diameter or radius of a circle.

Let's look at an example.

A circle has a circumference of 20.72 m. What is its diameter?

First, write down the formula.

c=πd

Next, fill in the values that you know.

20.72 m=3.14 d

Then, divide both sides of the equation by 3.14

6.6=d

The answer is the diameter is 6.6 meters.

astraxan [27]

Answer:

Each car weighs 2,265 pounds

Step-by-step explanation:

Given that the car carrier weighs 35,000 pounds when empty, that is, without cars, and that loading 7 cars its weight is 50,855 pounds, the difference between both values implies the weight of the 7 cars together, which is determined through the following calculation:

50,855 - 35,000 = X

15.855 = X

Thus, the weight of the 7 cars together is 15,855 pounds. In turn, the weight of each particular car is determined from the following division:

15.855 / 7 = X

2,265 = X

Therefore, each car weighs about 2,265 pounds.
