hi there
it will be 4÷3
because area of sphere and area of cylinder are given equal where height of sphere is equal to its radius also radius of sphere and circle are given equal so this all implies that we have to compare radius of sphere and height of circle.
(4÷3)πr^2h=πr^2h
(4÷3)h=h
(4÷3)r=h
now r od sphere = r of circle
height of circle is4÷3 of its radius
