B) Square the diameter and multiply by π.
C) Divide the diameter in half and multiply by π.
D) Divide the diameter in half, square, and multiply by π.

Answer 1

Sice we know the formula for the area of a circle is A=3.14 x a^2
where a=raidus we must first find the radius. Since we know the diamater D we can then take D/2 to get r. So the answer is D

Answer 2

the answer is d .first of all you have t o find the half of the diameter and then you can square it.
