Question

Help please

Answer 1

use the formula
circumference=2(pi)(radius)

Answer 2

i have no clue what that is

Answer 3

the tire is a circle, n the formula for circumference of a circle is 2(pi)(radius)
where pi=3.14

Answer 4

I dont get what you are saying

Answer 5

circumference of a circle is the length around it. the total length of the outer boundary of the circle is given to you i.e. 84.78 inches
and now you have to find the radius of this tire(the circle). And for that you have that formula of circumference. Do you know what radius is?

Answer 6

no

Answer 7

radius is a line segment from the center of a circle to the bpundary of that circle.

Answer 8

you have me lost

Answer 9

boundary*

Answer 10

still have no clue

Answer 11

this picture can help you with what, circumference and radius are.

Answer 12

no not really

Answer 13

the value of circumference is given to you in the question. the value of pi is 3.14
put the values in the formula and you will get the value of the radius.

Answer 14

I DON'T KNOW HOW TO DO THAT!!!!!

Answer 15

84.78=2(3.14)(radius)
84.78=(6.28)(radius)
radius=84.78/6/28
radius=13.5 inches

Answer 16

thanks you...
