Answer:
11 ft
Step-by-step explanation:
The equation for the volume of a cone is:
V = 1/3(3.14)r^2h
V = 414.48
r = 6
Plug in those values and solve for h:
414.48 = 1/3(3.14)(6)^2h
414.48 = 37.68h ; divide both sides by 37.68
11 = h
The missing height is 11ft.
Since the total circumference of the circle is 60 pi cm which passes around 360˚, the length of an arc of 140˚ will be equal to 140/360 = 7/18 times the total length:
l = (7/18) * 60 pi cm = 23.3 pi cm
Answer:
C. Biased, because she only asked students on honor roll.
Step-by-step explanation:
