Answer:
B
Step-by-step explanation:
Substitute the following values into the cylindrical volume equation below:
r= 30/2 = 15 cm
h = 320 cm
V=πr2h
V=(3.14)(15)^2 (320)
V=226 080 cm^3
The more dvds the more the height incresases
D. because PQR and XYZ are not congruent
Answer:
I think this could be the answer- x^ +2x-15
