Answer 2

Step-by-step explanation:

so let radius be = y cm

now volume of hemisphere

= {[4(pie)y^3]/3}÷2

and volume of cone will be

= [(pie)y^2 h]/3

so ratio of their volumes

= { [4(pie)y^3]/3×2} ÷[(pie)y^2 h]/3

= [2(pie)y^3]/3 × 3/[(pie) y^2 h]

= 2y/h

and volume of cylinder

(pie)y^2 h

so ratio

2y/h÷ (pie)y^2h

= 2/y(pie) answer
