Step-by-step explanation:

A) either radius or diameter and height

V = πR²h or πD²h/4

B) Radius is half a diameter, R = 4 cm

C) Rather depends on how they are put together.

Placing the rectangular faces touching would make a cylinder

D) V = 3.14(4²)(2) = 100.48  ≈ 100 cm³

i.e. V = ½πR²h

F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³

The tires on Miguel's bicycle have a diameter of 28 inches. How many feet has Miguel traveled when the tires complete 15 revolut
-BARSIC- [3]

Answer:

109.9 feet

Step-by-step explanation:

To find how many feet has Miguel traveled, we need to know the circunference of the tire:

C = pi*d = 3.14 * 28 = 87.92 inches

So, for each revolution of the tire, Miguel will travel 87.92 inches. So, to know the distance he will travel, we can do a rule of three:

1 revolution -> 87.92 inches

15 revolutions -> x inches

1/15 = 87.92/x

x = 87.92 * 15 = 1318.8 inches

As the question asks for the distance in feet, we convert from inch to foot by dividing the value of inches by 12, so:

distance in feet = 1318.8 / 12 = 109.9 feet
