Answer: 4.25 or 17/4 is the height
Step-by-step explanation:
V=pi*r^2*h
We set them equal to each other and solve for h
pi*3^2*17=pi*6^2*h
h=9*17/36=153/36=4.25=17/4
Answer:
62
Step-by-step explanation:
ΔABC is an isosceles triangle therefore ∡B = ∡C.
ΔDCA is a rectangular triangle therefore ∡y + ∡C = 90°
22° + ∡C = 90° |subtract 22° from both sides
∡C = 68°
Y=2(4)+8
y=8+8
y=16
Hope this helps :)
