Radius of sector
WebA simple way is to substitute the given values in the formula, Area of sector = (Arc length × radius)/2. Let us understand this with an example. For example, if the arc length of a circle is given as 15 cm and the area of the sector is 225 cm 2. We know that, Area of sector = (Arc length × radius)/2. After substituting the values in this ... WebJan 31, 2024 · arc length = r × θ. Then find the Perimeter of a Sector. Perimeter of sector = Radius (r) + Radius (r) + Arc length (l) Example: Determine the perimeter of a sector PRQ. Solution: Sector of circle radius = 42 cm. Angle of sector = 60 ∘. By using below formula, first convert the angle from degrees to radians.

WebSep 15, 2024 · In geometry you learned that the area of a circle of radius r is πr2. We will now learn how to find the area of a sector of a circle. A sector is the region bounded by a central angle and its intercepted arc, such as the shaded region in Figure 4.3.1. Let θ be a central angle in a circle of radius r and let A be the area of its sector. WebApr 6, 2024 · The radius is approximately equal to 1.785. The precise answer is √ (10 / π). To get this result, recall the formula area = π × r2. We transform it to the form r2 = area / π, and so we see that the radius is equal to the square root of area / π. Plugging in area = 10, we obtain: radius = √ (10 / π) ≈ √ (10 / 3.14) ≈ √3.185 ≈ 1.785.
