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.
Answer: 56.5
Step-by-step explanation:
We can't tell what any single dimension is, or what any pair of dimensions
are. But we can be sure that all three dimensions taken together are a set
of numbers which, when all multiplied together, result in a product of 1,000 .
