Acircle with a diameter of 10 inches is spanned by a central angle of 180 degrees. what is the length of the subtended arc?

since the diameter of the circle is 10, then its radius must be half that or 5.

The correct answer is 15.7 inches

Step-by-step explanation:

Points to remember

Circumference of a circle = 2πr

Where r is the radius of circle

To find the value of arc length

It is given that, diameter = 10 inches

Radius = diameter/2 = 10/2 = 5 inches

Circumference =  2πr

 = 2 * 3.14 * 5

 = 31.4

central angle of arc =180

Arc length = (180/360) * circumference

 = (1/2) * 31.4

 = 15.7 inches

Therefore the correct answer is 15.7 inches

c. the third graph

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
