The perimeter of a shape is the total length of its boundary. For a quadrant, which is a quarter of a circle, the perimeter includes the curved part plus the two straight sides. Perimeter is also used for fencing a property, sewing, and more. In this topic, we will learn about the perimeter of a quadrant.
The perimeter of a quadrant is the total length of its curved arc plus the two radii that form the straight sides. The formula for the perimeter of a quadrant is π = (ππ/2) + 2π, where π is the radius of the circle. For instance, if a quadrant has a radius of 6, then its perimeter is π = (3.14*6/2) + 2*6 = 9.42 + 12 = 21.42.
Letβs consider another example of a quadrant with a radius of 8. The perimeter of the quadrant will be: π = (π*8/2) + 2*8 = 12.56 + 16 = 28.56.
To find the perimeter of a quadrant, we use the formula that includes the arc length and the sum of the two radii. For instance, if a quadrant has a radius of 5, then the perimeter is: π = (3.14*5/2) + 2*5 = 7.85 + 10 = 17.85 cm. Example Problem on Perimeter of Quadrant - For finding the perimeter of a quadrant, we use the formula, π = (ππ/2) + 2π. For example, letβs say, the radius is 7 cm. Now, the perimeter = (3.14*7/2) + 2*7 = 10.99 + 14 = 24.99 cm. Therefore, the perimeter of the quadrant is 24.99 cm.
Learning some tips and tricks makes it easier for children to calculate the perimeter of quadrants. Here are some tips and tricks given below: Always remember that a quadrant's perimeter is the sum of the arc length and the two radii. Use the formula, π = (ππ/2) + 2π. Calculating the perimeter of a quadrant starts by determining the arc length, which is a quarter of the circle's circumference. To reduce confusion, clearly label the radius of the quadrant before applying the formula. To avoid mistakes when calculating the perimeter, ensure the value of π is consistent and the radius is accurately measured. If given the diameter instead of the radius, remember that the radius is half the diameter, which is essential for correct calculations.
Did you know that while working with the perimeter of a quadrant, children might encounter some errors or difficulties? We have many solutions to resolve these problems. Here are some given below:
A circular garden has a radius of 10 meters, but only a quarter of it is fenced. Calculate the required fence length.
Perimeter of the fenced quadrant = 25.7 meters.
Given radius = 10 meters. Perimeter of the quadrant = (ππ/2) + 2π = (3.14*10/2) + 2*10 = 15.7 + 20 = 35.7 meters.
A pie is cut into four equal parts, with each part representing a quadrant. If the pie's diameter is 16 inches, find the perimeter of one quadrant.
Perimeter of one quadrant = 22.56 inches.
Given diameter = 16 inches, so the radius is 8 inches. Perimeter of the quadrant = (ππ/2) + 2π = (3.14*8/2) + 2*8 = 12.56 + 16 = 28.56 inches.
A quadrant-shaped pond has a radius of 12 feet. What is the perimeter of the pond?
Perimeter of the pond = 37.68 feet.
Perimeter of the quadrant = (ππ/2) + 2π = (3.14*12/2) + 2*12 = 18.84 + 24 = 42.84 feet.
An artist is creating a quadrant-shaped sculpture with a radius of 5 feet. How much material is needed to cover the perimeter?
Material needed for the perimeter = 16.85 feet.
Perimeter of the quadrant = (ππ/2) + 2π = (3.14*5/2) + 2*5 = 7.85 + 10 = 17.85 feet.
A quadrant-shaped boardwalk has a radius of 15 meters. Calculate the perimeter.
Perimeter = 61.35 meters.
Perimeter of the quadrant = (ππ/2) + 2π = (3.14*15/2) + 2*15 = 23.55 + 30 = 53.55 meters.
Perimeter: The total length of the sides and arc of a quadrant. Quadrant: A quarter of a circle, bounded by two radii and an arc. Radius: The distance from the center of a circle to any point on its circumference. Arc: A part of the circumference of a circle. Formula of perimeter: The mathematical expression used to calculate the perimeter of a quadrant is π = (ππ/2) + 2π.
