Generally area of a quadrant = 1/4*π*r², and circumference of a quadrant = (πr)/2 + 2r, Where r is radius, Assume π = 3.14 Given that circumference of quadrant = 22 cm => πr + 4r = 44 cm, => r(π+4) = 44cm => r(7.14) = 44 => r is nearly 6.16 cm, If we can ignore the decimal value r = 6cm, (ii) Area = πr 2 or πd 2 /4 (iii) Area of semi-circle = πr 2 /2 (iv) Area of a quadrant of a circle = πr 2 /4 Answer: First double 3 feet to give a diameter of 6 feet. answered Oct 17, 2019 by Deepak01 (58.6k points) selected Oct 17, 2019 by Vikash Kumar . asked Aug 2, 2018 in Mathematics by vikashsoni (11.0k points) areas related to circles; class-10 ; 0 votes. Center: a point O of a circle from where all other points are equidistant. Equation: A = (pi)r^2. The area on the first quadrant of the circle x^2+y^2=36 is revolved about the line y+10=0. Answer: First, find the radius of the circle by dividing the circumfernece by Pi and halving the answer to give 3.501 to 3 decimal places. Here we are going to see the how to find area and perimeter of quadrant. The area of the sector can be obtained by multiplying the circle's area by the ratio of the angle θ (expressed in radians) and 2 π (because the area of the sector is directly proportional to its angle, and 2 π is the angle for the whole circle, in radians): A = π r 2 θ 2 π = r 2 θ 2. Example: Find the area of a quadrant Q of a circle C with radius 8 cm. Ex 12.3, 15 In figure, ABC is a quadrant of a circle of radius 14 cm and a semicircle is drawn with BC as diameter. Finally divide 254.34 by 4 to give 63.6 to 1 decimal place. If area of quadrant of a circle is 38.5 cm 2 then find its diameter (use π = 22/7) cbse; class-10; Share It On Facebook Twitter Email. The area of the element is approximated as the area of the triangle given by Fig. Area of circle= πr 2 = 3.14(8) 2 = 200.96 cm 2. Question: What is the area of the quadrant with a radius of 14cm ? Try it now. Now divide the answer by 4 as 90 degrees is 1/4 of the whole circle to give 4.7 feet to 1 decimal place. Area of 4 corners as quadrants of circle Area of remaining part = (area of rectangle – area of four quadrants of circles) = (300 – 38.5) m 2 = 261.5 m 2. Required fields are marked *.
