A gardener makes a new circular flower bed. The bed is fourteen feet in diameter. Calculate the circumference and the area of the circular flower bed.
A)circumference = 7pi feet, area = 49pi square feet
B)circumference = 14pi feet, area = 14pi square feet
C)circumference = 14pi feet, area = 49pi square feet
D)circumference = 14pi feet, area = 196pi square feet
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the diameter of the circle is 14 feet, so the radius is 7 feet. Plugging this value into the formula gives C = 2π(7) = 14π feet.
The area of a circle is given by the formula A = πr^2. Again, using the radius of 7 feet, we find A = π(7^2) = 49π square feet.
Therefore, the correct answer is C) circumference = 14π feet, area = 49π square feet.
