Answer:
$90.90
Step-by-step explanation:
The item normally costs $110.99. If the sporting goods store is offering a 10% discount, it means that the price including the discount will be:
$110.99 x 0.90 = $99.891.
the in-line skates cost with the discount $99.89, not including taxes.
The circumference is found by multiplying the radius by pi by 2
And then the arc length would be multiplied by the fraction of the circle..
So using what you wrote is correct, but the answer you got is incorrect.
2x 3.14 x 90 = 565.2 meters
565.2 x 90/360 = 141.3 meters
