Answer:
The diameter was
in.
Step-by-step explanation:
The arc of a circle is given by

where
s = arc length
r = radius of the circle
θ = measure of the central angle in radians.
From the information given
s = 4 in
θ = 32º
To find the diameter of the original pizza, we use the formula of the diameter of a circle

First, we need to convert the angle to radians

Next, solve for r from the arc formula

Then, we use the diameter of a circle formula

Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
