Answer:
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle
π is a constant whose value is 3.14
From the diagram,
Diameter = 16 inches
Radius = diameter/2 = 16/2 = 8 inches
Circumference = 2 × 3.14 × 8 = 50.24 inches
The formula for determining the circumference of a circle is expressed as
Area = πr²
Area = 3.14 × 8² = 200.96 inches²
