In the center of a circular field, there is a pole. The distance from the pole to the edge of the field is 20 meters. Nick would like to run around the edge of the circular field 6 times. How many meters will he have run in total ?

OpenStudy (anonymous):

Ok so the pole is the center of the circle right?

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

so that means 20 meters is the radius

OpenStudy (anonymous):

cause the center of any circle to the edge, is equivilant to the radius

OpenStudy (anonymous):

Yeah I agree

OpenStudy (anonymous):

Now do you know the formula for the curcumfirance of a circle?

OpenStudy (anonymous):

Um

OpenStudy (anonymous):

YOU CANT GIVE ANSWERS DIRECTLY THATS AGAINST THE RULES!

OpenStudy (anonymous):

ok so anyway

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

Now I'm confused @aahmed123

OpenStudy (anonymous):

ok listen

OpenStudy (anonymous):

the formula for the circumference of a circle is 2*pi*radius

OpenStudy (anonymous):

2radius is the diamiter right?

OpenStudy (anonymous):

Yeah 40 ?

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

no, 20 is the radius

OpenStudy (anonymous):

the diameter is 40

OpenStudy (anonymous):

and the formula for the circumference is C="pi"d

OpenStudy (anonymous):

I guess it could be...

OpenStudy (anonymous):

or Circumference is equal to pi times the diameter

OpenStudy (anonymous):

It's C = PI*D

OpenStudy (anonymous):

yup, pi is approximatley 3.14

OpenStudy (anonymous):

so do 40*3.14

OpenStudy (anonymous):

Kk

OpenStudy (anonymous):

so plug in 40x3.14

OpenStudy (anonymous):

you can to that equation

OpenStudy (anonymous):

BUT

OpenStudy (anonymous):

I got 125.6

OpenStudy (anonymous):

the question says he wants to run around SIX times not only once

OpenStudy (anonymous):

so multiply your answer by 6

OpenStudy (anonymous):

Kk

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

I agree with @aahmed123

OpenStudy (anonymous):

I got 753.6

OpenStudy (anonymous):

thats your answer :)

OpenStudy (anonymous):

Thank you SO OOOOO MUCH @aahmed123 & @heretoalwayshelp

OpenStudy (anonymous):

np :)
