Question

The diameters of two given circles are as 3 : 4, and the sum of the areas of the circles is equal to the area of a circle whose diameter measures 30 c. Find the diameters of the given circles.

Raju Garg · Answer

area of first circle = 22/7*(3x) 2 =22/7*9x 2 =198x 2 /7 area of second circle=22/7(4x) 2 =22/7*16x 2 =352x 2 /7 total area of circles = 198x 2 /7+352x 2 /7 = 550x 2 /7 area of third circle = 22/7*(30) 2 =22/7*900=19800/7 total area of circles = area of third circle 550x 2 /7 = 19800/7 550x 2 =19800 x 2 =19800/550=36 x = 6 diameter of circles = 6*3*,6*4* =18,24
