Answer: 3 units
Step-by-step explanation:
the volume of a cone C = πr²h/3
C = 18π, h =2x, r = diameter/2 = 2x/2 =x
18π = π* x²* 2x/3
divide through by π
18 = x² * 2x/3
multiply through by 3
54 = 2x³
divide through by 2
27 = x³
x =∛27 = 3
x = 3 units = radius
Answer:
Step-by-step explanation:
Starting with 3 x < -18, we divide both sides by 3, obtaining x < -6.
Draw a circle centered at x = -6 and then from that circle draw an arrow to the left.
So you are using Volume...
V=1/3(pi)r^2h
as you go thu this equation
15 x 15 =225
12 x12= 144
225-144= 81
81/9=9
which your piece would be 1/3 pi r^2h answer is 1356.48
and you round it to the nearest tenth. So
( 1356.5) is ur answer...... So (B)
