The formula of a lateral area of a cylinder:

We have r = 9 yd and H = 4 yd. Substitute:

Answer: its 4
Step-by-step explanation: i took the quiz just now
CD and DE are equal distance so their equations are equal:
2x+7 = 4(x-3)
2x+7 = 4x-12
Subtract 2x from both sides
7 = 2x-12
Add 12 to both sides
19 = 2x
9.5 = x
Now that u have x just plug it into the equation for DE
4(9.5-3)
38-12
26 is the answer
