The area of the sector formed by the arc of the circle is 14 square feet.
What is sector of the circle?
A sector of a circle is a pie-shaped section of a circle formed by the arc and its two radii. A sector is formed when a portion of the circle's circumference (as well known as an arc) and two radii cross paths at both endpoints of a arc. A sector of a circle has the shape of a pizza slice or even a pie.
- Two radii and an arc encircle a portion of a circle.
- A circle is divided into two segments which are referred to as minor sectors as well as major sectors.
- The major sector is represented by the larger portion of the circle, while the minor sector is represented by the smaller portion.
Now, according to the question;
Length of a sector is estimated by the formula = ∅×r
where ∅ is the angle formed by sector in radians and r is the radius of the circle.
Thus,
∅ = Length of a sector/r
The radius is r = 7 ft
The value of length of a sector = 4 ft
∅ = 4/7
∅ = 0.57 radians
Now, estimate the area of the sector.
area of a sector = (∅/2)×r²
Substituting the values.
area of a sector = (4/7/2)×7²
= (4/14)×49
area of a sector = 14 ft²
Therefore, the area of the sector is calculated as 14 ft².
