The formula for the area of a circle is
We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.
So the answer is B, 81 pi square feet
Answer:
D^1 should be (28,0)
Step-by-step explanation:
a dilation is performed by multiplying the x and y coordinates by the scale factor. D(7,0)... (7×4,0×4).... D^1(28,0)
