Question

Question 17
Maria races her bicycle for 94m. A wheel of her bicycle turns 47 times as the bicycle travels this distance. What is the diameter of the wheel?
Use the value 3.14 for pie. Round your answer to the nearest tenth. Do not round any intermediate steps.

Answer 1

this means that the wheel circumference multiplied by 47 equals 94

so, (dpi)47 = 94
do you know how to simplify it to get d?

Answer 2

anyways, you first divide 47 be each side, resulting
dpi=2
bc pi is 3.14
you divide 2 by 3.14
since it wants you to round to the nearest tenths
you can round 0.63694267515 to 0.6
hm @AZ, i feel like i did to wrong lol

Answer 3

*it

Answer 4

yeah, that's correct

we know that the circumference of her bike times how many times it turned is the total distance she travelled

so

circumference * 47 = 94

and the circumference formula is

C = 2* \(\pi\) * radius

or you could remember that 2 * radius is the diameter and get

C = \(\pi\) * diameter

Answer 5

so you're on the right track :)

Answer 6

2*47=94

Answer 7

so that means the circumference is 2

and so we have

circumference = 2 * pi
and we know pi is a constant which rounds to 3.14

Answer 8

6.28

Answer 9

oops sorry

Answer 10

I made a mistake

Answer 11

circumference is 2

2 = pi * diameter

Answer 12

0.636942675159

Answer 13

then round to the nearest tenth

Answer 14

0.6

Answer 15

ig lol
