Question

calculate the circumference of a circle whose area is equal to the sum of the areas of the circles with diameters 24cm,32cm,96cm.

Answer 1

sum of the areas of the circles with diameters 24cm, 32cm and 96 cm = 2805π cm2

hence, area of the circle to which radius is given as a query is 2805π cm2.

hence, πr2 = 2805π
r2 = 2805.
r = √2805
r = 52.96 cm
hence,
circumference = 2πr
= 2 × 3.14 × 52.96
= 166.29cm.
