To find the circumference and area of a pizza with a diameter of 16 inches, we can use the following formulas:
Part 1: Circumference
The formula for the circumference \( C \) of a circle is: \[ C = \pi \times d \] where \( d \) is the diameter.
Given:
- Diameter \( d = 16 \) inches
- \( \pi \approx 3.14 \)
Substituting the values into the formula: \[ C = 3.14 \times 16 = 50.24 \text{ inches} \]
Part 2: Area
The formula for the area \( A \) of a circle is: \[ A = \pi \times r^2 \] where \( r \) is the radius. The radius is half of the diameter.
Given:
- Radius \( r = \frac{16}{2} = 8 \) inches
Substituting the values into the formula: \[ A = 3.14 \times 8^2 = 3.14 \times 64 = 200.96 \text{ square inches} \]
Summary of Answers
- Circumference = 50.24 inches
- Area = 200.96 square inches
