The correct answer is -b+12
Answer:
D 81 pi units^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
18 pi = 2 * pi *r
Divide each side by 2 * pi
18 pi / (2 pi) = 2 pi * r/ (2 pi)
9 = r
Now we can find the area. Area is given by
A = pi r^2
A = pi * 9^2
A = 81 pi units^2
Answer:
The highest would be the letter B and the lowest would be letter C if the pat is what you need to know.
Hope it helps :)
I'm doing the exact same one an i got 48 cubic units for the volume. I still have to draw the rectangular figure though.
To find the ratio of centimeters to meters you need to divide 66 by 33 to get 2.
Then multiply 2727 by 2 to get 5454.
