A circle of radius = 7 or diameter = 14 or circumference = 43.98 cm has an area of: 1.5398 × 10 0 square kilometers (km²); 0.01539 square meters (m²) 153.9 square centimeters (cm²) Area of a circle = πr^2 π×diameter\2 × diameter\2 so , diameter^2\4 × π = 154 so , diameter^2 = 196 diameter = 14 cm Wish it helps : ) Find the area of the segment of a circle of radius 14 cm, if the length of the corresponding arc APB is 22 cm. Area of a Circle Formula. Radius of circle= 6/2=3. [Use π = 22/7] We have length of Arc = 22 cm, Hence, area of segment APBA = Area of sector (өAPBO) - Area of ∆AOB = (154 - 98)cm 2 Circle Multiple Choice Question 1. Using Radius to Find Area Identify the radius of a circle. Given, radius of circle = 5 cm. …, A committee of size 5 is to be selected at random from 3 chemists and 5 physicists. To find the radius substitute this value into the above formula and solve for the radius. d/dt(A) = d/dt(π*r 2) The left side is simple dA/dt the right side is not that easy. The radius is half the diameter. Radius of the circle, r = 14 cmThe chord AB subtends an angle 60o at the centre of the circle.Now, Area of the minor segment = Area of the sector AOB - Area of ΔAOB = 102.67 - 84.87= 17.85 cm2Now, Area of the major segment = Area of the circle - Area of the minor segment=616 - 17.8= 598.2 cm2 r^2= 154*7/22= 7*7cm. Example: find the area of a circle. Answer/ Explanation . The centroid divides the median of a triangle in the ratio 2:1. Then the area of the circle, correct to nearest c m 2 is. Use this easy and mobile-friendly calculator to compute the area of a circle given its diameter. A circle of radius = 14 or diameter = 28 or circumference = 87.96 cm has an area of: 6.1588 × 10 0 square kilometers (km²); 0.06158 square meters (m²) 615.8 square centimeters (cm²) D=Diameter. If the circumference of a circular sheet is 154 m, find its radius.
