Question

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

Answer 1

Answer:

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.

Answer 2

la answer es ocho=8 units
