In circle 0, the radius is 4, and the measure of minir arc ab is 120 degrees. find the lenght of minor arc ab to the newrest integer

8 units

Step-by-step explanation:

Note that 120 degrees represents 1/3 of 360 degrees.  The arc described here is thus 1/3 of the circumference of this circle.

Find this circumference and then multiply that result by 1/3:

The formula for the circumference of a circle with radius r is C = 2πr.  Here,

(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the answer is a
