two circles are there one with arc area 60 digree equal to 45 digree of another circle find the area of circle 1 : circle 2 ratio
area for first circle = ( 3.14 * r ^ 2 ) / 6 area of second circke = ( 3.14 * r ^ 2 ) / 8 therefore , ratio = 3 : 4 answer : a
divide(multiply(multiply(divide(45, const_360), 2), const_pi), multiply(multiply(divide(60, const_360), const_2), const_pi))
