Question

a drip irrigation system is installed around a circular flower garden that is 3 ft in diameter. if the irrigation system costs $5.33 per foot, find the cost to place the irrigation system around the flower garden. use 3.14 for $pi$. (round your answer to the nearest cent.)

Explanation:

Step1: Find the circumference of the circle.

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter. Given $d = 3$ ft and $\pi=3.14$, so $C=3.14\times3 = 9.42$ ft.

Step2: Calculate the cost.

The cost per - foot is $\$5.33$. Multiply the circumference by the cost per - foot. So the cost $=5.33\times9.42=5.33\times(9 + 0.42)=5.33\times9+5.33\times0.42=47.97+2.2386 = 50.2086\approx50.21$.

Answer:

$50.21$
