How do you find distance of a sector?

How to find the length of an arc and sector area: an example

  1. Decide on the radius of your circle.
  2. What will be the angle between the ends of the arc?
  3. Calculate the arc length according to the formula above: L = r * θ = 15 * π/4 = 11.78 cm .
  4. Calculate the area of a sector: A = r² * θ / 2 = 15² * π/4 / 2 = 88.36 cm² .

How do you find the degree of a sector?

The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.

What is the perimeter of sector?

The perimeter of a sector is the distance around a sector. We can calculate the perimeter of a sector by adding together the lengths of the two radii and the arc length of the sector.

What is the formula for finding the perimeter of a sector?

Perimeter of a sector-Formula

  1. So the formula for the perimeter of sector will be: 2r + (θ/360)*2πr = 2r[1 + (θ*π)/180]
  2. The range of value of the perimeter of a sector: 2r(2r + 2πr).
  3. A circle with a radius of 10 m has a sector making an angle of 60° at the center.

What is formula of perimeter of sector?

Perimeter of sector = 2 radius + arc length. Arc length is calculated using the relation : Arc length = l = (θ/360) × 2πr. Therefore, Perimeter of a Sector = 2 Radius + ((θ/360) × 2πr )

What is the perimeter of a sector with radius 10.5 cm and sector angle 60 degree?

Expert-verified answer radium is equal to the= r = 10.5 cm and the angle is equal to = x = 60 degree . So upon solving the perimeter of sector will be = 32 cm.

What is the formula for perimeter of sector?

The formula for the perimeter of the sector of a circle is [2r + ?/360o (2?r)] where r is the radius of the circle and ? is the angle of the sector.

What is the perimeter of sector formula?

What is perimeter of a sector?

The perimeter is the distance all around the outside of a shape. We can find the perimeter of a sector using what we know about finding the length of an arc. A sector is formed between two radii and an arc. To find the perimeter, we need to add these values together. Perimeter = Arc length + 2r.
