Find the area of the circle by using the formula. Use 3.14 as an estimate for pie. Then use an estimate to check whether your answer is reasonable.

The  formula for the area of a circle is 3.14*radius². The circumference is 3.14*twice the radius. If you have the diameter, but not the radius, divide the diameter by half and you get the radius. If you are still unclear, tell me what you are unclear about and I can help. If you provide me with a radius or diameter, I can give you the area or circumference with a step by step explanation. If you want me to find the radius or diameter from the area or circumference, I can give you a step by step explanation for it too. I hope this helps!

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
