Question

a landscaper installed a circular sprinkler system using 50.25 feet of copper tubing to create the circle. to the nearest whole foot, what is the diameter of the circular sprinkler? a) 4 feet b) 8 feet c) 16 feet d) 158 feet

Explanation:

Step1: Identify circumference value

The length of tubing is the circumference: $C = 50.25$ feet

Step2: Use circumference formula

Circumference formula: $C = \pi d$, solve for $d$:
$d = \frac{C}{\pi}$

Step3: Calculate diameter

Substitute values:
$d = \frac{50.25}{\pi} \approx \frac{50.25}{3.1416} \approx 16.0$

Answer:

C) 16 feet
