Answer:
87.965
Step-by-step explanation:
surface area of a cylinder,
2πr²+2πrh (where r = radius, h = height)
given, h = 5, r = 2
so,
2πr²+2πrh
= 2π×2²+2π×2×5
= 8π+20π
= 28π
= 87.9645943..
= 87.965 (rounded to the nearest thousand)
N^(7-3) = n^4
When dividing indices, you subtract the indices. If we multiply, you add them.
18*6=? think 6*10=60 then 6*8=48 then 60 + 48 =108 and that's your answer
