1.

cirles are 8cm and 6cm respectively. Find the radiusf(D) 2cmThe radi of twos ofwhich has arhasA) 14cmqual to the sum of the area of the two circles ?(B) 12cm(C) 10cm

Answer»

Sum of areas of the two circles is π[r1^2+r2^2]Sum=22/7((8)^2+(6)^2)=22/7(64+36)=22/7*100=π100cm^2Hence radius of a circle with sum of areas =πr^2=π100r^2=100r=10cmoption c
