Answer:
r = 10.72 cm
Step-by-step explanation:
h = 6 cm
Volume of cone = 722 cubic cm

Let the second side be equal to x
Then the first side is x-5
The third side will be x-5-2 = x-7
Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42
3x=44
X= 44/3
Therefore the second sides length is 44/3
The first sides length is 44/3 -5 = 29/3
The third side is 44/3 -7 = 23/3
I THINK IT IS B
B) D(X)= X-8x4
