That function is incorrect.
The correct function is . . . . C(f) = (5/9) (f - 32) .
If a Fahrenheit thermometer reads 52° ,
then a Celsius thermometer should read . . .
C (52) = (5/9) (52 - 32) =
(5/9) (20) = <em>(11 and 1/9)°C</em>.
Answer:
<em>The perimeter of the pizza slice is 20.1 cm</em>
Step-by-step explanation:
<u>Perimeter of a Sector of a Circle</u>
The arc length of a sector of a circle of radius r and angle θ is given by:
L = rθ
The angle must be expressed in radians.
The total perimeter of the circular sector, including the two radii, is:
P = rθ + 2r
The pizza slice has a radius of r=7 cm and a central angle of θ=50°
Converting to radians:

The perimeter is:

Calculating:
P = 20.1 cm
The perimeter of the pizza slice is 20.1 cm
