The radius of a circle is increased by 1

Webb22 aug. 2012 · Obviously the diameter/radius will increase. Not sure by how much though. Do the same thing for a ball the size of the earth. Add 1 meter to the string and (amazingly, at least to me) the increased radius/diameter is the same for a ball the size of the earth as for a small ball held in your hand.

Webbsince the area of circle depends only on its radius which is in the squared form i.e. πr^2 so the increment will happen two times. lets take initial area of circle = 100 unit. after two further increment area will be = 100×101÷100×101÷100= 102.01 unit. % change in area = (102.01–100)÷100×100. = 2.01%. WebbLet the radius of first sphere is r 1 and second sphere with increased radius is r 2. r 1 = r. When radius is incresed by 10 % r 2 = r + (10 r 100) = 1.1 r.
