Answer:
A=8.75 in.
Step-by-step explanation:
Since ∆ HBA & ∆HKJ are similar,
HB/HA = HK/HJ
3/5.25 = 8/HJ
3HJ/5.25 = 8
3HJ = 42
HJ = 14 in.
AJ = 14 - 5.25
AJ = 8.75 in.
Therefore
A=8.75 in.
I hope this helped you.
Answer:-1
Step-by-step explanation:You do reverse operation so negative 2Y means multiplication so you divide two -2 sides so positive two divided by -2 is -1
Answer:
the volume of the pipe is 649.98 cubic inches.
Step-by-step explanation:
We have been given that a collar of Styrofoam is made to insulate a pipe. We are asked to find the volume of the given pipe.
We will use volume of hollow cylinder formula to solve our given problem.

where,
R = Radius of external cylinder,
r = Radius of internal cylinder.
h = Height of cylinder.
substituting our given values in above formula, we will get:

Therefore, the volume of the pipe is 649.98 cubic inches.
