The circumference of a circle is given by the formula C = 2πr, where r is the radius.

So, substituting r = 279 and π = 3.14 in the formula, we get:
C = 2 * 3.14 * 279
C = 1750.92

Therefore, the approximate circumference of the circle with a radius of 279 is 1750.92.
what is the area?
The area of a circle is given by the formula A = πr^2, where r is the radius.

Substituting r = 279 and π = 3.14 in the formula, we get:
A = 3.14 * 279^2
A = 3.14 * 77841
A = 244482.74

Therefore, the area of the circle with a radius of 279 is approximately 244482.74 square units.
