Answer:
the volume of a cylinder = V=Ah =pirsqh
=pie × r sq × h
= 3.14×4 ×4×9 = 452.16 so thats eliminated?
Volume of a cone = V= 1÷3pirsqh
= 1/3×3.14×4×4×9 = 150.72
volume of cylinder = 2×pi×r×h+2×pi× r×r
=241.645
not sure choose the ones you think a closest?
Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
