Answer:
The answer is 615 inches
Step-by-step explanation:
The formula for solving the area of a circle is :
A= 1/4 π d^2
So since we only know the diameter the formula would be:
A= 1/4 of 3.14 x 28^2
- The first thing you need to do is square 28 which is 784
- Them times 784 by 3.14 which is 2461.76
- After all that, your equation should look like this: A = 1/4 of 2461.76
- So then you would times 2461.76 by 1/4 which is 615.75216 or 615.75
Hope this helped :)
