Question

Check my work..?

Answer 1

This stuff is really easy, but I just wanna know if I did everything right..

Answer 2

A carnival ride is in the shape of a wheel with a radius of 20 feet. The wheel has 16 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.

Answer 3

My work:

The central angle will be 360/16 or 22.5.

The arc length will be Circumference/16.

Circumference = 2 pi r

C = (2)(3.14)(20)

C = (6.28)(20)

C = 125.6

So the arc length is 125.6.

Area of sector is Area of circle/16

Area = pi r^2

A = (3.14)(20^2)

A = (3.14)(400)

A = 1256

So the area of the sector is 1256/16 or 78.5.

Answer 5

I got 78.5 So yes you are correct.

Answer 6

Thanks, but that's not the whole question..

Answer 7

I think you forgot to divide the circumference by 16 to get your arc length... :)

Answer 8

Oh, that's right..lol. :P

Answer 9

I believe that's it..

Answer 10

yes, it really seems like the steps preformed are correct. Unless there is a mistake in calculating, but otherwise everything should be fine!

Answer 11

Thanks!

Answer 12

I thought that arc length was a bit big xD

Answer 13

Haha! ^.^
