Question

two concentric circles have radii of 14 cm and 7 cm respectively find the area of space between them

Answer 1

Area of circle with bigger radius= pi*r*r

Area= 22/7*14*14

Area= 616m^2

Area of circle with smaller radius= pi*r*r

Area= 22/7*7*7

Area= 154m^2

THerefore, area between them = 616-154

Area= 462m^2
