Feb 26, 2024 · To find the perimeter of the quadrant OACB, we need to calculate the lengths of the curved arc ACB and the two straight radii OA and OB. Asked Nov 20 at 15:30 Report Sep 29, 2025 · Question i Concepts Quadrant of a circle, Perimeter of composite figures, Pythagoras theorem, Arc length Explanation OABC is a quadrant of a circle with radius 8 cm. In given figure, OABC is square of side 7 cm. (Use π = 22 7). 20 cm b. So, for finding the perimeter of the quadrant, we have to take one-fourth of the circumference of the circle. Dec 4, 2018 · Answer: 11 cm² Step-by-step explanation: The formula for the circumference of a circle = 2πr Since 4 quadrants make a circle, their perimeter is only 1/4th that of teh circle. 4K subscribers Subscribed Oct 8, 2024 · Concepts: Geometry, Circle, Perimeter Explanation: To find the perimeter of the quadrant OACB, we need to consider both the arc length ACB and the two radii OA and OB. Solution: Given, Radius (r) = 8 cm Area of circle= πr 2 = 3. Perimeter of quadrant = 2 π r 4 + 2 r 42πr +2r. By signing up, you'll get Jan 25, 2023 · Given the radius of the circle is 10cm, we can plug in the values: C = 2π (10) = 20π To find the perimeter of a quarter of the circle, we divide the circumference by 4: Perimeter = C/4 = 20π/4 = 5π cm So the perimeter of a quarter of the circle with a radius of 10cm is approximately 15. Perimeter of the circle is = 2 × 22 = 44 c m The perimeter of a circle with radius is 7 cm is 44 cm. To use the Dec 8, 2022 · OACB is a quadrant of a circle with centre O and radius 3. The triangular part OABC is removed. Perimeter of shaded region = OD + DC + arc CB Step-By-Step Solution Step 1: Find OC (radius) Given: OC = OA = OB = 8 cm Step Jan 8, 2025 · Question Anjali draws the shape of a sweet candy which is in the shape of a quadrant OABC and a semicircular region with OB as its diameter. = 2 × 22 7 × 7 4 + 2 × 7 = 44 4 + 14 = 11 + 14 = 25 cm = 42× 722 × 7 +2× 7 = 444 +14 = 11+ 14 = 25 cm. 71 cm. Feb 25, 2024 · To find the perimeter of a quadrant with a 7 cm radius, you calculate ¼ of the circle's circumference and then add the lengths of the two radii, rounding the final result to (c. Oct 1, 2018 · area, circle, circle formula, circumference, diameter radius, shape, shapes associated of circles, Singapore Primary School mathematics, teaching methods, PSLE In the figure alongside, OAB is a quadrant of a circle. From the figure, OC=radius of the circle ⇒OC=7cm Thus, the area of the shaded region, A s is, A s =area of quadrant - area of ODC ⇒ A s = 1 4 π r 2 − 1 2 OD OC ⇒ A s = 1 4 π 7 2 − 1 2 4 7 ⇒ A s =38. Use the Pythagoras theorem for the triangle formed by the sides and diagonal of the rectangle and then find the breadth of the rectangle. 14 × 3 4 + 2 × 3 = 18. Approach: Calculate the area of the quadrant OACB and subtract the area of the triangle ODB to find the area of the shaded region. Perimeter is the distance around a two-dimensional shape. 4 cm Step-by-step explanation: Area of the Quadrant A quadrant is one-fourth of a circle. The perimeter of the quadrant is.
