Answer:
V≈12308.8
Step-by-step explanation:
V=πr2h
V=(3.14)(14)2(20)
R=14cm
H=20cm
π=3.14
15/14 lies between 1 and 2
Pretty sure it’s A. Have a great night
So the radius is 5 cm
and we are given the volume at 225 cm³
now breakdown the volume formula for a cone which is V equals 1/3 Bh
b= pi r squared
now substitute everything in
225 equals 1/3 pi(5)^2 Times h
since we don’t know H that is what we’re solving for
225= 1/3 pi(25) times h
multiple 3/1 on both sides to cancel the 1/3
675= 25(3.14) times h
675= 78.5 (h)
h= 675/78.5
h=8.60 cm
0.065/4 is 0.01625. 0.01625 is your answer.
