Answer:
first setup your problem. it should look like this :
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: 7.84 is the answer
Answer:
B is the answer i just took the oddyseyware lesson and got 100%
Sqrt(200) is about 14
so S is the best representation for the value for sqrt(200)
