The diameter of a bicycle wheel is 63 cm. How much distance will it cover in 20revolutions?

alina1380 [7]

Answer:

1256 cm

Step-by-step explanation:

First we must find the perimeter, because the perimeter is equal to 1 revolution.

The perimeter of any circle is Pi(Diameter)

3.14*20

62.8 cm is the perimeter of the bike wheel.

Because the perimeter is basically a revolution, we can multiply 62.8 by 20 to get:

1256 cm

A cylinder has a diameter of 10 inches in the height four times the radius what is the volume

SVEN [57.7K]

Answer:

500π in^3

Step-by-step explanation:

The radius is half the diameter, so the radius is 5 in. Since the height is four times that, the height is 20 in.

The equation for the volume of a cylinder is:

$V = \pi r^{2}h$

We can plug in the radius and height:

$V = \pi \times (5)^{2} \times 20\\V = \pi \times 25 \times 20\\V = 500\pi in^{3}$
