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
It is:
40+1+0.3+0.02=41.32
4,5 is the answer I think
30 because the original ratio would be 16 to 14 but that reduces to 8 to 7 and then you just double the 7 to get 14 and then you add 16 and 14 together to get the total number of horses and elephants.
I would have to say 2.3 but i dont know the real answer thats what i calculated
