Step-by-step explanation:
7p³r² - 14pr³ = 7pr²(p²-2r)
5 4/5 divided by 2 1/4=
change to decimals:
5.8/2.25=2.57
change 2.57 to fraction: about 2 3/5
so, the estimate for the length is 2 3/5
let me lie down this prism.
Check the picture below.
so the prism is really 6 rectangles stacked up to each other at the edges, so we can simply get the area of each rectangle and sum them up.

Answer:
d=1/2
Step-by-step explanation:

Hello,
When you have a polygon inscribed in a circle, the opposite angles are supplementary.
So we can start by saying that A + C = 180. Or x + 3x = 180. This gives us a value of 45 for x.
If we input that in for angle B, we get: 2(25) - 10 = 80.
If angle B = 80, then angle D must be 100, because the angles are supplementary.
Good luck,
