5 is 33 because the question ends up being 14+3+16
A cell has a radius: r = 3 nmThe surface area of a cell:A = 4 r² π = 4 · 3² π = 4 · 9 π = 36 π nm²The volume of a cell:V = 4/3 r³ π = 4/3 · 3³ π = 4 · 9 π = 36 π nm³Answer: The surface area is 36 π nm² and the volume is 36 π nm³.
So the students are on 5:6 ratio from volleyball to football, and we know there are 220 students in total.
just multiple the numbers.
for example 7×7 is - 49y
and 3×16 is - 48y
