Answer:
Option 4 is your answer.
Step-by-step explanation:
your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)

3 times 6=18
now we have
3-18+2
add
3-18=-15
now we have
-15+2=-13
answer is -17 because of order of operations (PEMDAS)
Answer:
729 * 10^-45
Step-by-step explanation:
Here, we want to expand the value based on the exponent
We have the power multiplying every term in the bracket
That would be;
9^3•10^-45
= 729 * 10^-45
