Howmany cups of sugar should be usedfor 2 cups of boiling water?​, If p denotes the percentage increase in the number of the first generation immigrants from 19952005, and q denotes the percentage increase inthe total Find the perimeter of the triangle. (Take π = 22/7) Solution:-From the question it is given that, Circumference of the circle = 154 m. Then, To find the radius substitute this value into the above formula and solve for the radius. Then, Area of the circle = πr 2 = 22/7 × 5 2 = 22/7 × 25 = 550/7 = 78.57 cm 2. 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 Area of circle =3*3*22/7. The area of a square inscribed in the circle is 98 cm². That's. During a hike, Angelo drank 3 liters of water. (in this case the area of a circle) A = π*r 2. What is the area of a circle with a DIAMETER of 5 cm (radius of 2.5 cm)? Log in. Given : If the area of a circle = 154 cm².
