A bicycle tire has a radius of 11 inches. To the nearest inch, how far does the tire travel when it makes 7 revolutions?

484 Inch

Step-by-step explanation:

Radius of the tire=11 inch

The distance which the tire covers in 1 revolution is the circumference of the tire.

Circumference of a circle=2πr

Therefore:

Distance of the tire in 1 revolution=2*π*11=22π inches

From the above, we can then determine the distance which the tire travels in 7 revolutions.

Distance if the tire in 7 revolutions=7*22π

=483.81 Inch

≈484 Inch ( to the nearest inch)

The tire travels approximately 484 Inch in 7 revolutions.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
