Are these correct? 1. Drag the "V" to angles that form a vertical pair from the stairs above
2. Drag the "AI" to angles that form an Alternate Interior Pair from the stairs above
3. Drag the "AE" to angles that form an Alternate Exterior Pair from the stairs above
4. Drag the "C" to angles that form a Corresponding Pair from the stairs above

1.) 900 = 3(300)
Therefore, pyramid B is 3 times bigger than pyramid A.

2.) Volume of silo = volume of cylinder + volume of hemisphere = 22/7 x 8^2 x 172 + 2/3 x 22/7 x 8^3 = 34,597.57 + 1,072.76 ≈ 35,669 ft^3

3.) Required volume = volume of cone - volume of bubble gum = 1/3 x 22/7 x (1.75)^2 x 3.5 - 4/3 x 22/7 x (0.25)^3 = 11.229 - 0.065 = 11.164 ≈ 11.15
