Evaluate

\frac{22}{7} \times 2 r = 440

Evaluate

More Steps

\frac{44}{7} r = 440

Multiply both sides of the equation by LCD

\frac{44}{7} r \times 7 = 440 \times 7

Simplify the equation

44 r = 440 \times 7

Simplify the equation

44 r = 3080

Divide both sides of the equation by 44

r = 70

Square both sides of the equation

r^{2} = 7 0^{2}

To covert the equation to rectangular coordinates using conversion formulas,substitute x^{2} + y^{2} for r^{2}

x^{2} + y^{2} = 7 0^{2}

Solution

x^{2} + y^{2} = 4900
