So we want to know what x times 2 is. So think about this: multiply x with 2. We can find out what works and what doesn’t. So remind yourself that if you are multiplying a negative number, you get a negative. And when you minus a negative with a positive it’s the same as a negative + a negative. So it can’t be a negative as the answer is 0. Try each positive and you will find the answer to be

Find the length of the arc on a circle with a radius of 2.4 kilometers and is intercepted by a central angle measuring 150°. lea
Kaylis [27]

If the radius of the circle exists 2.4 kilometers and is intercepted by a central angle measuring 150° then the length of the arc exists 5π inches.

<h3>What was the relation between the central angle and its intercepted arc?</h3>
  • If the vertex of an angle exists in the center of the circle and the two sides of the angle are radii in the circle, then this angle exists named a central angle.
  • Each central angle exists subtended by the opposite arc, the name of the arc exists the starting point and the finish point of the angle.
  • There exists a relation between the central angle and its subtended arc the measure of the central angle equals half the measure of its subtended arc.
  • The length of the subtended arc relies on the measurement of its central angle and the length of the radius and the measure of the arc.
  • The measurement of the circle exists at 360°.
  • The length of the circle exists at 2πr.

The radius of the circle r = 2.4 kilometers

The measure of the central angle exists at 150°.

The length of the arc = central angle/360 × 2πr

The length of the arc = 150°/360° × 2 × π × 2.4 = 2π

The length of the arc exists 2π kilometers.

Kazeer [188]
What do you mean by model?

60 times .15 is 9.

A model could be like 50 circles with 9 circles filled in, or a circle with 15% shaded in.
