Answer:
[tex]12.5 \pi\ ft[/tex] or [tex]39.25\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
In this problem we have
[tex]D=12.5\ ft[/tex]
substitute
[tex]C=\pi (12.5)=12.5 \pi\ ft[/tex]
assume [tex]\pi =3.14[/tex]
[tex]12.5 \pi\ ft=39.25\ ft[/tex]
Answer:
39.27 feet.
Step-by-step explanation:
We are asked to find the fence needed to enclose a pool with a diameter of 12.5 feet.
[tex]\text{Circumference of circle}=\pi D[/tex], where D represents diameter of circle.
[tex]\text{Circumference of circle}=\pi\times \text{12.5 feet}[/tex]
[tex]\text{Circumference of circle}=39.2699\text{ feet}[/tex]
[tex]\text{Circumference of circle}\approx 39.27\text{ feet}[/tex]
Therefore, 39.27 feet of fence is needed to enclose the pool.
