Find the missing height
Eva8 [605]

Answer:

h = 39.8 inches

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

We know the diameter d = 32 so the radius is 1/2 of the diameter

r = d/2=32/2 = 16

32000 = pi (16)^2 h

32000 = 256 ( pi) h

Divide each side by 256 pi

32000 / 256 pi = h

125/pi = h

Using 3.14 for pi

39.8089172 = h

Rounding to the nearest tenth

h = 39.8 inches

Find the density of a soda can with a radius of 3.25 cm, a height of 122 cm, and a mass of 40 g.
dimaraw [331]

Answer:

density = 9.88*10^{-3} g/cm^3

Step-by-step explanation:

Step 1: Volume of soda can

volume = \pi r ^{2}  h

=> \pi 3.25^{2}*122

volume = 4048.3cm^{3}

Step 2: Using answer from step 1 to calculate density

density=\frac{mass}{volume}

density = \frac{40}{\pi 3.25^{2}*122  }

density = 9.88*10^{-3} g/cm^3

Which of the following statements are true of the hypotenuse of a right triangle?
OLEGan [10]
The hypotenuse is always the longest side, and it is always opposite the right angle. 
"Leg" is not a mathematical term. If it is being used to refer to one of the sides forming a right angle, the hypotenuse is not a "leg".
