Well it says show your answer in km so yea, them I am right? or.. ?eXg.

Pi x Diameter = Circumference
Next divide 100,000 by your Circumference. and the whole number is your answer. 442
SC2 you are correct my dear sir.
72=d btw I'm not figuring this out by calculator and clicking the pi button we are using 3.14 as pi not 3.141592653589793238462643383....
so lets say 72 x pi = 226.08cm, you want to convert cm to km so you multiply ... right?? not divide?

What's so hard about grade 10? Canadian Highschool in its entirety is a joke. Most chill 4 years of my life. Enjoy it while it lasts...Not that my school is that much harder now, but I don't have near the amount of free time that I did in high school.Ground Zero wrote:He he, thought I reconized the question - oh I was just curious. Reminds me of good ol' grade 9. Dude if you hate grade 9, grade 10 is going to be an epic kick in the ass !!eXg. TrueGift wrote:I am in grade 9, why

C = pi * 2 r
226.194 = 3.14 * 2 * 36cm
rock hits ground 1 time every 226.194cm of the distance
distance = 1km = 1000m = 100,000cm
100,000cm/226.194cm=revolutions in 1 mile or number of time rock hits ground
442 revolutions or 442 times
Units dont matter they cancel.....
