V(t) = πr^2h
V'(t) = π(2rr'h + r^2h')
V'(t) = π(2(5)(-2)(7) + 5^2(8)
V'(t) = π(-140 + 200)
V'(t) = 60π in^3
Answer:
70
Step-by-step explanation:
180-40=140/2 = 70
Answer:
C.
Step-by-step explanation:
A triangle has a full measure of 180° and a right triangle has a 90° angle so you add 90° (C) plus 48° (A) and then subtract it from 180° and you should get 42° :)
Step-by-step explanation:
look at the picture ok :)
