A mountain bike has a diameter of 26 inches. To the nearest foot how far does the tire travel when it makes 32 revolutions?

Tcecarenko [31]

Hello!

You have to find the circumference

You use the equation

$2 \pi r$

r is radius which is half the diameter

This gives us 81.68

Multiply this by 32

81.68 * 32 = 2613.76

This is 217.8133333 feet

The answer is 217.8133 feet

Hope this helps!

10) The figure below is a regular octagon. What is the least number of degrees that the octagon must be rotated clockwise around

From the following figure:

Because the center angle measure 45 degrees, we must rotate 3 times 45 degrees to get point D.

In other words, we must rotate

$3\cdot45=135$

that is 135 degrees clockwise.

Please help me with this homework

The answer is 1.25.

The equation for slope is rise over run. Y is the rise and X is the run. The point equation is (y2-y1)/(x2-x-1) = slope.

Plugging in the numbers: (-4-1)/(-4-0) = 1.25
