Solution for 8pi=2pi*r equation:


Simplifying
8pi = 2pi * r

Multiply ip * r
8ip = 2ipr

Solving
8ip = 2ipr

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-2ipr' to each side of the equation.
8ip + -2ipr = 2ipr + -2ipr

Combine like terms: 2ipr + -2ipr = 0
8ip + -2ipr = 0

Factor out the Greatest Common Factor (GCF), '2ip'.
2ip(4 + -1r) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'ip' equal to zero and attempt to solve: Simplifying ip = 0 Solving ip = 0 Move all terms containing i to the left, all other terms to the right. Simplifying ip = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(4 + -1r)' equal to zero and attempt to solve: Simplifying 4 + -1r = 0 Solving 4 + -1r = 0 Move all terms containing i to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1r = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1r = 0 + -4 -1r = 0 + -4 Combine like terms: 0 + -4 = -4 -1r = -4 Add 'r' to each side of the equation. -1r + r = -4 + r Combine like terms: -1r + r = 0 0 = -4 + r Simplifying 0 = -4 + r The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
