Best ResponseYou've already chosen the best response.0A carnival ride is in the shape of a wheel with a radius of 25 feet. The wheel has 20 cars attached to the center of the wheel. What is the central angle, arc length, and area of a sector between any two cars? Round answers to the nearest hundredth if applicable. You must show all work and calculations to receive credit.

Best ResponseYou've already chosen the best response.1now you draw a circle and divide the circle into 20 parts so what will you get 20 angles

Best ResponseYou've already chosen the best response.1now A circle has a measure of 360 degrees. We have 20 angles in that circle. What does one angle measure, then?,

Best ResponseYou've already chosen the best response.1good. Now do you know how central angles relate to their arcs?

Best ResponseYou've already chosen the best response.1Ok, well I am going to tell you and don't forget ok, cuz this is important and you will continue to use this fact throughout your years of math. The formula to find the arc length (which is not the same as the arc measure) is lenght of the arc=measure of the arc/360 * 2pi *radius :))))

Best ResponseYou've already chosen the best response.1Here we don't know the arc length so we fill in everything we do know and solve for the length. so , lenght of the arc=18/360* 2*pi *25

Best ResponseYou've already chosen the best response.1That is correct unless you have to leave your answer in terms of pi, which is 2.5pi, then.

Best ResponseYou've already chosen the best response.1Now for the area of the sector.....

Best ResponseYou've already chosen the best response.1That also has a formula,

Best ResponseYou've already chosen the best response.1its's arc lenght /360 = pi r^2

Best ResponseYou've already chosen the best response.1The area formula for a sector of our circle is as follows: 18/360 * pi* r^2
