Answer: The circumference of the plate = 51.86 inches.
Step-by-step explanation:
Given : The radius of a round plate = 8.25 inches
Formula: circumference of a circle = [tex]2\pi r[/tex] , where r = radius of circle .
Then, the circumference of the plate [tex]=2\times\dfrac{22}{7}\times8.25[/tex] [ [tex]\pi=\dfrac{22}{7}[/tex] ]
[tex]=51.857142857\approx51.86\ \text{inches}[/tex]
Hence, the circumference of the plate = 51.86 inches.
