The diameter of a circle extends from (-100,3) to (20,3). If the area of this circle is the same as a square, what is a side length of that square?

@timo86m help please?

How do you find area of a circle :D

OpenStudy (ineedhelp10):

It's Area= (radius)^2

OpenStudy (anonymous):

pir^2

jigglypuff314 (jigglypuff314):

pi * (radius)^2

OpenStudy (ineedhelp10):

this is sorta like the other problem we did right? @jigglypuff314

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (ineedhelp10):

so i'll square it and all that correct?

OpenStudy (anonymous):

jiggllllly pufffff jiggglllyyyyy

OpenStudy (anonymous):

use your distance formula to find the radius

jigglypuff314 (jigglypuff314):

square root after finding the circle's area

OpenStudy (ineedhelp10):

and i got 14400

jigglypuff314 (jigglypuff314):

diameter = distance of (-100,3) to (20,3) = 120 so radius = 1/2 * 120 = 60 so area of circle = 60^2 * pi area of square = 60^2 * pi side of square = square root(60^2 * pi) = 60√pi

OpenStudy (ineedhelp10):

and how would i figure out one side of the square?

jigglypuff314 (jigglypuff314):

area of square = 60^2 * pi side of square = square root(60^2 * pi) = 60√pi because (side of square)^2 = area of square

Okay thanks(:
