1 answer

Radius (r) = 279 inches

Using the formula for circumference:
Circumference = 2 * π * r
C = 2 * 3.14 * 279
C = 1751.52 inches

Using the formula for area:
Area = π * r^2
A = 3.14 * 279^2
A = 3.14 * 77841
A = 244346.74 square inches

Therefore, the circumference of the circle with a radius of 279 inches is 1751.52 inches and the area is 244346.74 square inches.
