Explanation:
The circumference of a circle can be calculated using the formula: C = 2πr
where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14159), and r is the radius of the circle.
Given that the radius of the circle is 7ft, we can substitute this value into the formula and get: C = 2π(7ft) C = 14πft
So the circumference of the circle in terms of π is 14πft.
