The circle's circumference is used to determine that:
The railing needs to be replaced for about 7.1 feet.
Given a circle with radius r, the circumference is equal to:
C = 2r
It is equivalent to 360º.
In this problem, the diameter is of 30 feet, hence the radius is 15 feet, so:
C = 2(15) = 30
The length that needs to be replaced is then determined by:
Considering that the circumference is equal to 360 degrees,
L = x 30 = 7.1
The railing needs to be replaced for about 7.1 feet.
I understand that the question that you are looking for is:
"A circular pool has a diameter of 30 feet. A section of the top railing with a central angle of 27° is broken and needs to be replaced. What approximate length of railing needs to be replaced? Round your answer to one decimal place."
<h3>What is the circumference of the circle?</h3>
The length of a circle's perimeter is known as its circumference. The length of the boundary, if the circle is split open and made straight, will equal the circle's circumference. A circle is made up of many points that are evenly spaced apart from one another; this single point is referred to as the circle's center.
