Question

this time i don't know the answer, but i give a medal.
What is the diameter of a cone with height 8 m and volume 150m3 ? (1 point)
7.5 m


15 m

Answer 1

A: 7.5 m
B: 5 sqrt 3 m
C: 7.5 sqrt 3 m
d: 15 m

Answer 2

V=(1/3)(pi)(r^2)(h)
150=(1.05)(r^2)(8)
150=(8.38)(r^2)
150/8.38=r^2
17.9=r^2
sqrt(17.9)=r
4.23=r
d=2r
d=8.46

Answer 3

?

Answer 4

volume of cone = 1/3 Pi r^2 h
so: 150=1/3* Pi *r^2* 8
so r^2=450/(8Pi)=18
r=sqrt18 and diameter = 2sqrt18=6sqrt2

Answer 5

answer 15
