Question

the diameters of two circles with Centre A and B are 16 cm and 30 cm respectively if area of a circle with Centre C is equal to the difference of areas of the other two circles then find the circumference of the circle with Centre c​

Answer 1

Answer:

Area of circle A = 22/7×8×8=1408/7

Area of circle B = 22/7×15×15=4950/7

Area of circle C = 4950/7 - 1408/7

= 3542/7=506

Area of circle C = 22/7×radius square

506×7/22 = radius square

Radius = root 141
