Answer:

V = PI*r2h

In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.

Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.

V = pi * r2 * h

= pi * 32 * 5

= pi * 9 * 5

= 3.14 * 45

= 141.37 cubic inches

Step-by-step explanation:

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.

Some to do. So do it.​
viktelen [127]

Answer:

1. A=42

L=14

42=W(14)

divide both sides by 14

3=W

2. A=96

L=12

96=W(12)

divide both sides by 12

8=W

3. A=90

L=18

90=W(18)

divide both sides by 18

5=W

4. A=1.50

L=15

1.50=W(15)

divide both sides by 15

0.1=W

Amy and her family were traveling during their vacation. She looked at her watch at point 1 in the diagram below, and then again
Juli2301 [7.4K]

The unit rate of the car is simply the average speed of the car between the two points.

The unit rate of the car is 40 miles per hour

From the diagram (see attachment), we have:

  • The distance between the two points is: 80 miles
  • The time spent to cover this distance is: 2 hours

<h3>The unit rate</h3>

So, the unit rate is:

Rate = \frac{Distance}{Time}

This gives

Rate = \frac{80\ miles}{2\ hours}

Simplify the quotient

Rate = 40\ miles/hour

Hence, the unit rate of the car is 40 miles per hour
