Sin x = cos (90-x)
eg sin 42 = cos(90-42) = cos 48
so the answer is B
Answer:
1. cone
radius, height = 2, 10
volume = 13.33
2. hemisphere
radius= 14
volume = 1829.33
Step-by-step explanation:
The region described has a radius r=2−y/5, therefore, the volume is a cone
radius, height = 2, 10
volume =
= 13.33
2. The region ∫14 0 π(196 - h^2) dh has a radius 196 - h^2, so the volume is a hemisphere
radius = 14
volume
=
=
=1829.33
5g2 + 10g + 2
