Find the circumference and multiply it by 3.

C = pi * d

C = 3.14 * 21

C = 65.94

So it travels 65.94 inches in 1 revolution.

65.94 * 3 = 197.82

So it travels 197.82 inches in 3 revolutions.

What is the slope of the line that passes through the points (-2,5) and (3,-4) in the standard (x,y) coordinate plane
Scorpion4ik [409]

To find the slope between two coordinates, you use the formula:

m = y2 - y1/x2 - x1

If coordinate A is (-2, 5) and coordinate B is (3, -4), then:

y2 = -4

y1 = 5

x2 = 3

x1 = -2

So, just substitute the points into the formula.

m = -4 - 5/3 - (-2)

m = -9/5

The slope of the line is -9/5.
