Question

Find the area of a quadrant of a circle whose perimeter is 22 cm

Answer 1

Hello here is your answer..
Formulas used = 
1. Circumference = 2 pie r
2. 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
