peach pie in a 9.00 in diameter plate is placed upon a rotating tray. Then, the tray is rotated such that the rim of the pie plate moves through a distance of 183 in. Express the angular distance that the pie plate has moved through in revolutions, radians, and degrees. angular distance: revolutions angular distance: radians angular distance: ∘ If the pie is cut into 9 equal slices, express the angular size of one slice in radians, as a fraction of π. angular size=π×

Explanation:

It is given that,

Diameter of the peach pie, d = 9 inches

Radius of the pie, r = 4.5 inches

The tray is rotated such that the rim of the pie plate moves through a distance of 183 inches, d = 183 inches

Let [tex]\theta[/tex] is the angular distance that the pie plate has moved through.

It is given by :

[tex]\theta=\dfrac{d}{r}[/tex]

[tex]\theta=\dfrac{183}{4.5}[/tex]  

[tex]\theta=40.66\ radian[/tex]

Since, 1 radian = 57.29 degrees

[tex]\theta=2329.64\ degrees[/tex]

Since, 1 radian = 0.159155 revolution

[tex]\theta=6.47124\ revolution[/tex]

Hence, this is the required solution.
