Abicycle wheel with radius 26" rotates through an arc that measures 80°. what is rhe length of the arc of the tire that touched the ground? 2.88π inches,
5.87π inches or 11.56π inches.

Step-by-step explanation:

In other words, what is the arc length if the central angle is 80° and the radius is 26'?

The arc length formula is s = r·Ф, where Ф is the central angle in radians.

We must therefore convert 80° to radian measure:

80°·π/180° = 1.396 radians, and so

arc length = s = r·Ф becomes    s = (26")(1.396 rad) = 36.3 inches

                                                    s  = 11.56π inches (3rd given possible

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
