Answer:

Radius = 11.94 ft

Diameter = 23.88 ft

Circumference = 75 ft

Step-by-step explanation:

Given:

Perimeter of the circular fence that surrounds the pool = 75 ft

To find the diameter, radius and circumference of the fence.

Solution:

Since perimeter of a circle is the length of the circumference of the circle, therefore the circumference of the circle will be = 75 ft

Formula for perimeter of circle = [tex]2\pi r[/tex]

where [tex]r[/tex] represents the radius of the circle.

We have:

[tex]2\pi r =75[/tex]

Using [tex]\pi=3.14[/tex]

[tex]2(3.14)r =75[/tex]

[tex]6.28r =75[/tex]

Dividing both sides by 6.28 to find [tex]r[/tex]

[tex]\frac{6.28r}{6.28} =\frac{75}{6.28}[/tex]

∴ [tex]r =11.94\ ft[/tex]

The diameter of a circle is given as twice the radius.

Thus diameter [tex]d=2r=2(11.94)=23.88\ ft[/tex]
