Aroad bike has a wheel diameter of 622 mm. what is the circumference of the wheel? use 3.14 for mc015-1.jpg

1953.08 mm

Step-by-step explanation:

We know that circumference of a circle is given by ;-

, where r is the radius of the circle.

Given: the diameter of the wheel = 622 mm

Then, the radius of the wheel =

Now, the circumference of the wheel is given by ;-

Hence, the circumference of the wheel =1953.08 mm.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

add an image, and i will answer
