Area and Perimeter Unit Test
Complete the table by finding the circumference and area of a circle with a radius of 279 inches. Substitute 3.14 for pi. Express your answers to the hundredths place.
Radius: 279 inches
Circumference: C = 2 * pi * r
C = 2 * 3.14 * 279
C = 1750.92 inches
Area: A = pi * r^2
A = 3.14 * (279)^2
A = 3.14 * 77841
A = 244412.74 square inches
Therefore, for a circle with a radius of 279 inches:
- Circumference = 1750.92 inches
- Area = 244412.74 square inches
