Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
vfiekz [6]

The measure of the Central Angle indicated is; 45°

<h3>How to find the central angle of a circle?</h3>

The central angle will be the angle subtended at the center by arc FE and arc CB.

Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;

Central Angle = 180° - 135° = 45°

Angle subtended by Arc CD at the center is;

θ = 180 - (81 + 45)

θ = 54°

A solid plastic ball is a sphere with a radius of 8 inches. How much plastic does it take to make one ball
mihalych1998 [28]

Answer:

2144.66in³

Step-by-step explanation:

Radius = 8 inches.

To determine the amount of sphere to make the ball, we'll have to find its volume.

Volume of a sphere = 4/3 * Πr³

V = 4/3*Πr³

Π = 22/7

V = 4/3 * 22/7 * 8³

V = 2144.66inches³

V = 2144.66in³

The amount of plastic required is 2144.66in³.

Before a strength and conditioning program, Susan could throw a softball 53 feet. After one season in the program, she could thr
jasenka [17]

Hi!

We will find the solution like this:

76 - 53 = 23 that's the difference in numbers, so now we have to find the percentage of this difference related to throwing the ball before strength and conditioning program, like this:

23/53 = 0,434 = 43,4%

The correct answer is B. 43,4%.

Hope this helps!
