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

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
