C = Pi x diameter.
C = 3.14 x 2
C = 6. 28

A = Pi x radius^2
Radius = 1/2diameter
Radius = 1
Area = (3.14)(1^2)
Area = 3.14

Finding the area and circumference of a circle is pretty easy, actually. You just need to be comfortable with the formulas. Hope this helped!

Drew is driving out of state to go to a theme park. The total distance he is driving is 500.34 miles. He has driven 0.45 of the

alexgriva [62]

The calculation is not reasonable, because 0.45 is less tha 1/2 ( 0.50) and what he has for an answer is half the distance ( 250.17 is 1/2 of 500.34).

To find actual mileage, multiply by 0.45:

500.34 x 0.45 = 225.153 miles.

Round the answer as needed.
