Question

Im not sure how to do these math problems. I really need some help can someone please help me figure out how to do these i really need to get a good grade and most important i want to be able to do this in the future.

Answer 1

these problems require you to relate a circle to a line.

Spose a circle has a circumference of 5 feet, if an ant walking along the circle goes completely around it 3 times .... how far would the ant have traveled?

Answer 2

number 4 is just giving you a ratio:\[360^o:15min\]
find the degrees turned for the stated minutes is then a proportion of:
\[\frac{360^o}{15min}=\frac{d^o}{t~min}\]
\[\frac{360^o*t~\cancel{min}}{15~\cancel{min}}=d^o\]

Answer 3

having difficulty with the last one. but i believe the first one is 15 feet ??

Answer 4

the ant? yes it will travel 15 feet :)

Answer 5

your question #1 has the same concept, they are simply asking for the circumference of each wheel

Answer 6

you say your having trouble with the "writing in math" problem?

Answer 7

if so, multiply the number of cars by the number of passengers each car can hold .... subtract to find the difference. Does the difference equal 28*60?

Answer 8

well i dont know what to multiply to find out how far a person travels on one turn of the ferris wheel that is my first problem. secondly for all the problems im not sure what i multiply to get the answer please tell me what im suppose to multiply because i dont understand the chart they give clearly

Answer 9

the circumference of a circle is determined by the formula: \(2\pi~r\) correct?

Answer 10

they give you the radius measurements in the chart for each ferris wheel

Answer 11

yes pi = 3.14

Answer 12

so i multiply pi with the radius for the answer 1 ?

Answer 13

they give diameter in the chart, so radius is half the diameter

Answer 14

well, 2pi times the radius yes

Answer 15

wait i dont see radius

Answer 16

hold on ... you need to remember some terminology that relates to a circle

Answer 17

all i see is diameter
and height

Answer 18

diameter is the longest chord of a circle, its the circles "width". A radius id defined as half the diameter .. half the width.

In determining the Circumference (the distance around a circle) we have 2 formulas that are essentially the same.

\[C = d~\pi=2(\frac{d}{2})~\pi =2r~\pi\]

so in this case, just multiply the diameters by pi

Answer 19

youll prolly have to google how many feet in a mile to solve the 2nd problem

Answer 20

the longest chord of the circle is 264 right ?

Answer 21

thats height of a ferris wheel

Answer 22

the chart reads: diameter = 250, and 328

Answer 23

264 ??

Answer 24

hello?
