Question

Mrs. Edwards drew three circles on the board as seen in the diagram below.
Which measurement is closest to the area of the largest circle in square yards?
A.615.75 yd²
B.21.99 yd²
C.43.98 yd²
D.153.94 yd²
(Explanation Please)

Answer 1

A=pi•r^2 (this is the equation for the area of a circle)
So the diameter is the line going through the circle which in this case is 14… but we need the radius which is half of that being 7
A=pi•7^2
Which would be approximately
153.94
So D ✅

Answer 2

Answer:

d

Step-by-step explanation:

A=pi•r^2 (this is the equation for the area of a circle)

So the diameter is the line going through the circle which in this case is 14, but we need the radius which is half of that being 7

A=pi•7^2

which will be about

153.94
