yup
no, the area of a circle equals pi times the radius squared or circumference times diameter over four.
it equals x1 it equals x1
So what is the question?
-2a^2
x^(2)-16=0 Take the -16 over to the other side of the equal sign, the -16 will turn +16. x^(2)=16 Then take the squared root of both sides. x=4
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
It equals to 3 over 2
What equals two over one
162.
It equals 3.25
It equals 2.842696629.
it equals eight * * * * * No, it does not! Four over thirty two equals an eighth or one over eight!
