Find the area of a circle with diameter 18in . Use the value 3.14 for pie , and do not round your answer. Be sure to include the correct unit in your answer.

254.34

Step-by-step explanation:

The formula for the area of a circle is :

The radius is the length from the side to the centre.

Pi=3.14

In order to work out the area you would first need to work out the radius. You can do this by dividing the diameter of 18 by 2, this gives you 9. This is because the radius is half of the diameter.

Now that we have worked out the radius the next step is to work out the area. You can do this by multiplying pi by the radius of 9 squared, this gives you 254.34 inches squared.

1) Divide 18 by 2.

2) Multiply pi by 9 squared.

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4
