jhonyy9:

why is B. ?pls check it

jhonyy9:

you ve forgot the denominator of 3

Joe2019:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 you ve forgot the denominator of 3 \(\color{#0cbb34}{\text{End of Quote}}\) so it is not b?

jhonyy9:

maybe B. than the formula of volum of a sphere is 4pir^3 without denominator

jhonyy9:

but there is again this 3 in denominator so in this way one 3 from numerator will be simplified by 3 from denominator what result from this ?

@supie

jhonyy9:

(3*10^2)^3 = 3^3 *10^6 this is true but not is this the correct answer bc. there is this 3 in denominator of formula for volum of a sphere what mean that one 3 will be simplified from numerator so the right answer will be 4pi*3^2 *10^6 so choice A.
