Find the volume of the triangular prism described below.
Luda [366]

The volume of the prism 121.6 cube in.

Step-by-step explanation:

Given,

The base is right angle triangle whose two sides are equal.

So,

Base (b) = 8 in

Another side of right angle triangle (l) = 8 in

Height (h) of the prism = 3.8 in

To find the volume of the prism.

Formula:

V = \frac{1}{2}bhl

Now,

V = \frac{1}{2}×8×8×3.8 cube in

= 121.6 cube in.

What is the velocity in inches per second of a roll that has a speed of 140 rpm and a diameter of 2.4 cm?
fgiga [73]

Answer:

The velocity in the border of the roll is 0.025 m/s.

Step-by-step explanation:

We have a roll that has an angular velocity of

\omega = 140\, rpm

The tangent velocity (of the edge of the roll) can be calculated as

V=\omega * r=\omega * D/2\\\\V=(1/2)*140\frac{1}{min}*2.4\, cm*\frac{1m}{100cm}*\frac{1min}{60s}\\\\V=0.028\,m/s

The velocity in the border of the roll is 0.025 m/s.

What is the width of a rectangular prism with a length of 13 feet, volume of 11232 cubic feet, and height of 36 feet?
Fynjy0 [20]

Answer:

24 ft.

Step-by-step explanation:

Volume (V) equals the product of length (l), width (w), and height (h)

V = l × w × h

Plug in the measurement you have into the equation

      11232 = 13 × w × 36

Multiply 13 and 36

      11232 = 468 × w

Divide both sides by 468

      24 = w
