52/4 = 13
$13 = 1 hour.
$6.50 = halfhour
13 x 3 = $39
She would have to work for 3 hours to earn $39
Answer:
ow do you find arc length without the radius?
To calculate arc length without radius, you need the central angle and the sector area:
Multiply the area by 2 and divide the result by the central angle in radians.
Find the square root of this division.
Multiply this root by the central angle again to get the arc length.
The units will be the square root of the sector area angle.

Or the central angle and the chord length:
Divide the central angle in radians by 2 and perform the sin function on it.
Divide the chord length by double the result of step 1. This gives you the radius.
Multiply the radius by the central angle to get the arc length.

Hello there, and thank you for posting your question here on brainly.
Short answer: C. Product of 2 rational numbers = a rational number.
Why?
The numbers are both rational because squared is a result of a number multiplied by itself. Like (3^2 = 9). It turns out as a rational number because you're multiplying by two positive numbers, which always turns out as a rational number. (3^2 * 4^2 ==> 144) [3^2 = 9] [4^2 = 16]
Hope this helped you! ♥
