Answer» Formulas used =1. Circumference = 2 pie r2. Area of Quadrant = 1/4 Pie r² Circumference = 2 Pie r 22 = 2 * 22/7 r r = 22 * 7 / 22 * 2 r = 7/2 or 3.5 cm Area Of Quadrant = 1/4 Pie r² = (1/4) * (22/7 ) * 3.5 * 3.5 = 1 * 22 * 35 * 35 / 4 * 7 * 10 * 10 = 1 * 11 * 35 / 4 * 10 = 9.625 cm² Hit like if you find it useful!

Answer»

Formulas used =1. Circumference = 2 pie r2. Area of Quadrant = 1/4 Pie r²

Circumference = 2 Pie r 22 = 2 * 22/7 r r = 22 * 7 / 22 * 2 r = 7/2 or 3.5 cm

Area Of Quadrant = 1/4 Pie r² = (1/4) * (22/7 ) * 3.5 * 3.5 = 1 * 22 * 35 * 35 / 4 * 7 * 10 * 10 = 1 * 11 * 35 / 4 * 10 = 9.625 cm²
