So what we know is that 15 is the diameter
However the formula to find the area of a circle is A=
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=7.5²
Then after we find what 7.5² is we get A=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
