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
The answer is 132.665 rounded is 132.67
area= r2 × π
13÷ 2 = 6.5
6.5 × 6.5 = 42.25
42.25 × 3.4 = 132.665 ------> 133.67
area= r2 × π
13÷ 2 = 6.5
6.5 × 6.5 = 42.25
42.25 × 3.4 = 132.665 ------> 133.67
