what is the area and circumference of a circle with a radius of 3 feet
The area of a circle with radius r is given by the formula A = πr^2. Substituting the radius r = 3 feet into the formula, we get:
A = π(3)^2
A = π(9)
A = 28.27 square feet
The circumference of a circle with radius r is given by the formula C = 2πr. Substituting the radius r = 3 feet into the formula, we get:
C = 2π(3)
C = 6π
C = 18.85 feet
Therefore, the area of the circle is 28.27 square feet and the circumference is 18.85 feet.
