Solution for s=7*3.14*s*h+7*3.14*(s*s) equation: 


Simplifying
s = 7 * 3.14s * h + 7 * 3.14(s * s)

Multiply 7 * 3.14
s = 21.98s * h + 7 * 3.14(s * s)

Multiply s * h
s = 21.98hs + 7 * 3.14(s * s)

Multiply s * s
s = 21.98hs + 7 * 3.14(s2)

Multiply 7 * 3.14
s = 21.98hs + 21.98s2

Solving
s = 21.98hs + 21.98s2

Solving for variable 's'.

Reorder the terms:
-21.98hs + s + -21.98s2 = 21.98hs + 21.98s2 + -21.98hs + -21.98s2

Reorder the terms:
-21.98hs + s + -21.98s2 = 21.98hs + -21.98hs + 21.98s2 + -21.98s2

Combine like terms: 21.98hs + -21.98hs = 0.00
-21.98hs + s + -21.98s2 = 0.00 + 21.98s2 + -21.98s2
-21.98hs + s + -21.98s2 = 21.98s2 + -21.98s2

Combine like terms: 21.98s2 + -21.98s2 = 0.00
-21.98hs + s + -21.98s2 = 0.00

Factor out the Greatest Common Factor (GCF), 's'.
s(-21.98h + 1 + -21.98s) = 0.00


Subproblem 1
Set the factor 's' equal to zero and attempt to solve:

Simplifying
s = 0

Solving
s = 0

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

Simplifying
s = 0

Subproblem 2
Set the factor '(-21.98h + 1 + -21.98s)' equal to zero and attempt to solve:

Simplifying
-21.98h + 1 + -21.98s = 0

Reorder the terms:
1 + -21.98h + -21.98s = 0

Solving
1 + -21.98h + -21.98s = 0

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

Add '-1' to each side of the equation.
1 + -21.98h + -1 + -21.98s = 0 + -1

Reorder the terms:
1 + -1 + -21.98h + -21.98s = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -21.98h + -21.98s = 0 + -1
-21.98h + -21.98s = 0 + -1

Combine like terms: 0 + -1 = -1
-21.98h + -21.98s = -1

Add '21.98h' to each side of the equation.
-21.98h + 21.98h + -21.98s = -1 + 21.98h

Combine like terms: -21.98h + 21.98h = 0.00
0.00 + -21.98s = -1 + 21.98h
-21.98s = -1 + 21.98h

Divide each side by '-21.98'.
s = 0.04549590537 + -1h

Simplifying
s = 0.04549590537 + -1h
Solution
s = {0, 0.04549590537 + -1h}
