The radius is the distance from the center point of a circle to the "edge" of the circle. To calculate the circumference you use the formula: C=(D)(pi)...D stands for distance from one end of the circle to the other through the center point - basically the distance is the radius of any circle just doubled.

By knowing the properties of circles, the circle with a <em>central</em> angle ACB of 48° and the <em>arc</em> length AB is 144 inches has a circumference of 1080 inches.

<h3>How to determine the circumference</h3>

According to the <em>Euclidean</em> geometry, the <em>circular</em> arc (s), in inches, is directly proportional to the <em>central</em> angle (θ), in radians:

s = θ · r   (1)

Where r is the radius of the circle, in inches. Please notice that the arc is directly proportional to the <em>central</em> angle and that the circumference is determined for a <em>central</em> angle of 360° (2π). Hence, we can determine the circumference of the circle by using the following relationship:

s/144 in = 360°/48°

s = (144 in) · (360°/48°)

s = 1080 in

By knowing the properties of circles, the circle with a <em>central</em> angle ACB of 48° and the <em>arc</em> length AB is 144 inches has a circumference of 1080 inches.

Which expression is equal to (x+2)(−3x2+3x+1)?
padilas [110]
Multiply everything in the second parenthesis by x.

-3x^3 + 3x^2 + x

Multiply everything in the second parenthesis by 2.

-6x^2 + 6x + 2

Combine these two equations together.

-3x^3 + 3x^2 + x - 6x^2 + 6x + 2

Combine like terms.

-3x^3 - 3x^2 + 7x + 2

Hope this helps!
