Question

Find the standard form of the equation of the circle with the given characteristics.
Center at origin; radius: 7√2

Answer 1

okay...its x^2 +y^2=98

Answer 2

thanks..how did u find the radius?

Answer 3

hmm..do u know the general form of a circle?

Answer 4

i meant how did you find r^2?

Answer 5

u had given the radius there as 7 sqrt(2)..just take a square of it & you'll get 98 :)

did u understand now?) :)

Answer 6

diameter | 14 sqrt(2)~~19.799
area | 98 pi~~307.876
perimeter | 14 sqrt(2) pi~~62.2004

Answer 7

ok i get it now

Answer 8

good :)
