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
This is how I do it. If it is a negative minus a negative, I combine the two - signs to make it an addition problem. Ex. -3 - -4 makes -3+4. The answer would be one.
If it is a negative plus a negative, keep the sign on the greater number and take away the sign the smaller number. Ex. -7 + (-9). Keep the sign on the 9. -7 - 9. The answer would be -16.
