1.	What will be the ratio of diameter of a hemisphere and the length of its circumference?
Answer» Let the radius of the hemisphere be r unit `therefore` its diameter =2r Also the circumference of the hemisphere=`(pir+2r)` unit. As per question , 2r:`(pir+2r)=2r:r(pi+2)=2:(pi+2)` Hence the ratio=2:`(pi+2)`.
