a. Double the diameter and multiply by π
b. Multiply the diameter by π
c. Square the diameter and multiply by π
d. Divide the diameter in half and multiply by π
e. Divide the diameter in half, square the radius, and multiply by π

Answer 1

correct... A=pi*d or R squared.

Answer 2

Well to find the area of a circle Pie times r^2. But If you already have the diameter, you could either split the diameter in half, and do the regulaur formula, OR you could ude this formula ----> Pie times The diameter
