Use the formula for radian measure to calculate the measure of a central angle in a circle having a radius of 12 cm and intercep
1 answer:
The central angle has a measure of radians calculated by the formula for radian measure is 1.75 radians.
<h3>What is the formula for radian measure?</h3>The formula for radian measure to calculate the central angle is given as,
Here, (r) is the radius of the circle and (θ) is the central angle.
In a circle having a radius of 12 cm and intercepting an arc of 21 cm. Put the value of radius and the length of the arc in the above formula as,
Thus, the central angle has a measure of radians calculated by the formula for radian measure is 1.75 radians.

Just graph the coordinates
this picture is the different quadrants on the graph, whichever quadrant the coordinate is in, is what you put in the 2nd column
for example: (-2,-3) is in the 3rd quadrant
if its not in a quadrant its either on x or y axis, so its just on the line, and i assume you know which axis is which
for number 4. You just do subtraction, and then if its negative, it becomes positive since its asking for the absolute value
for example: |-24-11| > |-35| > 35
