Problem: Using the formula fraction of the circle x circumference = arc length. Find length of minor arc AB.

The length of minor arc AB = 12.56 units.

Step-by-step explanation: The circle x has its circumference given as 2Pi x r.

A fraction of the circle is given as O/360,

Where O is the angle subtended at the center of the arc AB.

The length of an arc can be calculated by the formula;

Length of arc = O/360 x (2Pi x r)

Length of arc = 60/360 x (2 x 3.14 x 12)

Length of arc = 1/6 x (6.28 x 12)

Length of arc = 12.56 units.

Therefore the length of minor arc AB = 12.56 units

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
