However the formula to find the area of a circle is A=[tex] \pi [/tex]r² So to convert the 15 in diameter to a radius you have to do 15÷2,which is equal to 7.5
Now we know that the radius is 7.5. So what we do now is A=[tex] \pi [/tex]7.5² Then after we find what 7.5² is we get A=[tex] \pi [/tex]56.25 Then what we do is 3.14×56.25, because pi= 3.14. So when we do 3.14×56.25, we get 176.625 So the answer is A= 176.6 in²
