Answer:
132.73
Step-by-step explanation:
the equation for area of a circle is A=πr*2
if your diameter is 13 simply take half of that and plug into the equation
π(6.5)*2 which when put into a calculator comes out to 132.732289
This in the simplest form will be 2/15. You cannot divide this answer by anything which means it is in its simplest form!

Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55
