Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5
(4/3) Pi r^3 = (1/3) Pi r^2 h
Solving for h = 4r
Answer: true
Step-by-step explanation:
Answer:
907.46cm
Step-by-step explanation:
Area of Cirlce = πr^2
R= 17
R^2= 289
289 x 3.14 = 907.46
907.46cm
21 / 32 = (3/4) * (1/2) * height
21 / 32 = (3 / 8) * height
21 / 32 * (3 / 8) = height =
63 / 256 inches
