the volume of a cylinder is 24 π cubic feet.what is the volume of a cone having the same base and same height?
dalvyx [7]

\bf \stackrel{\textit{volume of a cylinder}}{V=\pi r^2 h}~\hspace{7em}\stackrel{\textit{volume of a cone}}{V=\cfrac{\pi r^2 h}{3}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{volume of a cylinder}}{V=24\pi }~\hspace{7em}\stackrel{\textit{volume of a cone}}{V=\cfrac{24\pi }{3}}\implies V=8\pi


notice the volumes, the cone's volume is really one-third that of the cylinder, assuming "h"eight and "r"adius is the same on both.

The Perimeter of a rectangle is 194 cm. The length of the rectangle is three centimeters less than four times the size of width.
Rus_ich [418]
Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20

So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm

Answer: Length=77 cm and width=20 cm

A jar contains balls numbered 1 to 10. Two balls are drawn with replacement. What is the probability that both balls are numbere
Elenna [48]

Answer:

Step-by-step explanation:

The number of ways that you can draw 2 balls without restriction is 10 * 10 = 100

Two balls will give you 2 or less (meaning 1) or 2*2 = 4

Four ways are possible

2  and 2

2 and 1

1 and 2

1 and 1

4/100 = 1/25 is the probability of making this happen.
