Final answer:
The radius of a circle with a circumference of 60ft is approximately 9.55 ft, and the diameter is approximately 19.10 ft. The formulas used are C = 2πr for circumference and D = 2r for diameter, where π is pi (approximately 3.14159).
Step-by-step explanation:
To find the radius and diameter of a circle with a circumference of 60ft, you can use the formulas C = 2πr and D = 2r, where C is the circumference, r is the radius, and D is the diameter of the circle. Here, π (pi) is approximately 3.14159.
To find the radius, rearrange the formula for circumference to solve for r:
C = 2πr
r = C / (2π)
r = 60ft / (2 × 3.14159)
r ≈ 9.55 ft
Once you have the radius, finding the diameter is straightforward:
D = 2r
D = 2 × 9.55 ft
D ≈ 19.10 ft
