The radius r of the circle is 4.4 yd .
What is sector of circle?
A circular sector, also known as circle sector or disk sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.
What is length of arc?
For a circle, the arc length formula is θ times the radius of a circle.
Arc Length = 2 π r (θ/360°)
where,
r = radius of circle
θ = angle of Sector
According to the question
Arc Length of circle = 16.3 yd
Angle of sector= 240°
By using arc length formula
Arc Length = 2 π r (θ/360°)
substituting the value
16.3 = 2π r (240°/360°)
16.3 = 2π r * [tex]\frac{2}{3}[/tex]
16.3 * 3 = 4π r
54.9 = 4π r
As π = [tex]\frac{22}{7}[/tex]
54.9 = 4 * [tex]\frac{22}{7}[/tex] r
54.9 * 7 = 88 r
384.3 = 88 r
r = 4.4 yd
Hence, The radius r of the circle is 4.4 yd .
