Circumference Formula: C = 2πr

• r is radius

Area of a Circle Formula: A = πr²

• r is radius

Step-by-step explanation:

Step 1: Define

Identify given.

C = 16.3 in

Step 2: Find Radius r

1. [Circumference Formula] Substitute in C:
   16.3 in = 2(3.14)r
2. [Division Property of Equality] Divide 6.28 on both sides:
   r = 2.596 in

Step 3: Find Area

1. [Area of a Circle Formula] Substitute in r:
   A = 3.14(2.596 in)²
2. Evaluate:
   A = 21.1611 in²
3. Round:
   A ≈ 21 in²

∴ we have found the area of the plate.
