1. Last summer, 80 students signed up for a summer trip to Washington, D. C.
This summer, 94 students signed up. To the nearest percent, what is the
percent change in the number of students who signed up for the trip?
A 2%
B 14%
C 15%
D 18%

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
