Hello,
For the first one, why did you divide again by 100 ?
Hi there people, need help again! with simple stuff like these!
Here's the first set of questions from a math book...
The diamter of a motorcycle wheel is 65cm
a) Work out the distance, in metres, the motorcycle travels when the wheel makes 100 complete turns.
: For this one I think worked it out and here is what I have got...
65 x PI = 204.203.. x 100 = 20420.35.. ÷ 100 = 204.2 (please correct me if wrong
For the next question I really got confused:::
b) Work out the number of complete turns the wheel makes when the motorcycle travels 500m.
.... confused SO MUCH, how do I work this OUT! PLEASE HELP!
I understand all the stuff about circumference, PI, radius, diameter, area, semi-circle, but when I come upon to these question of car tyres etc. I really get confused, any tips and ideas on how to mastermind this out???
THANKYOU! FOR YOUR HELP!
Well the question says, the wheel makes 100 complete amount of turns, therfore I have X it by 100, then I have divided by 100 because the question says to give the answer in meters, and the question started off by cm. I think I am right or wrong? can you help me with the 2nd 1 please???
hi there another question i want to ask....
There is a normal sized cylinder given, which says at the bottom of it, Base=75cm2 and 9cm. The question says, What is the area of the base?
What is the length? and What is the volume? I got really confused with this question, because it says BASE, im stupid I dont understand this, please help anyone!!!
