Solve 360=9(10r 9) 9

Evaluate

360 = 9 (10 r \times 9) \times 9

Evaluate

More Steps

360 = 7290 r

Rewrite the expression

- 7290 r = - 360

Divide both sides of the equation by - 90

81 r = 4

Square both sides of the equation

(81 r)^{2} = 4^{2}

Evaluate

6561 r^{2} = 4^{2}

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

6561 (x^{2} + y^{2}) = 4^{2}

Evaluate the power

6561 (x^{2} + y^{2}) = 16

Solution

6561 x^{2} + 6561 y^{2} = 16
