The answer that you are looking for is 2
We know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere
if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere
if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere
examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area
2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area
3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area

Answer:
5 weeks its 40 divided by 8
Step-by-step explanation:
Let's find the decimal value of each letter choice.
Choice A: This choice is already in decimal value.
Choice B: To turn this into a decimal, divide this by 100%. You get 0.4. This matches with choice A.
Choice C: To turn this into a decimal, divide this by 100%. You get 0.04. This does not match with A and B.
Choice D: 2/5 can be turned into 40/100. 40/100 can be converted into the decimal of 0.4. This matches with choices A and B.
Thus, the only different answer choice is C. That's your answer. I hope this helps! :)
