Answer:
Step-by-step explanation:
1. Traditionally, a standard dinner plate has always had a diameter of 10.5 inches. In recent years, however, increasing numbers of restaurants have chosen to use larger 11 or 12 inch plates.
2. 2 cm
The radius of the round plate is 2 cm. If the plate is being heated then both the radius and the area of the plate get expanded. We assume the radius of the plate as “r” and the area of the plate as A. We know that the area of a circular plate with radius r is $A=\pi {{r}^{2}}.
3. Eight-inch plate diameter times “pi”= a little over 25 inches. 9-inch plate times “pi” = a little over 28 inches. 10-inch plate times “pi” = 31.4 inches of circumference! See the math pattern: diameter of the plate times pi= circumference!
