Answer:
648pi
Step-by-step explanation:
V=pi*r^2*h
V=pi*9^2*8
V=pi*81*8
V=648pi
Area = 4.5 x 4.5 = 20.25 in²
Perimeter = 4 x 4.5 = 18 in
I think its D but im not sure
Answer:
8/12 yard or 2/3 yard
Step-by-step explanation:
The sum of the two lengths is ...
5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd
This fraction can be reduced by removing a factor of 4 from numerator and denominator.
8/12 yd = 2/3 yd
If the arm portions are end-to-end, the total length is 2/3 yard.
