When multiplying powers with the same base but different exponents, just add the exponents together. Note: this can only work if the base is the same. Note2: you can do the same with dividing powers by subtracting the exponents instead of adding.
Ex: 1. 2^7*2^2 (2 is the base, 7&2 are the exponents.
2^7*2^2 = 2^9 (add 7&2)
2^9 = 512

Answer:
117.8
Step-by-step explanation:
Surface area = πr²+πrl (whee r = radius and l = slant height)
= π×3²+π×3×9.5
= 75π/2
= 117.8
I believe the answer is 40%. I hope this helps!
