Answer:
Step-by-step explanation:
Let the numbers of steps you can take to reach your goal be x
Your goal is to take at least 10,800 steps per day and you have walked 7370 steps already.
x + 7370 >= 10800
x >= 10800 - 7370
x >= 3430
Answer:
S = 2π(4)^2 + 2π(4)(16)
Step-by-step explanation:
The surface area of a cylinder can be found using this equation: 2(πr^2) + 2(πrh). Therefore the answer would be the first one: S = 2π(4)^2 + 2π(4)(16)
Check the picture below.
so.. simply, use the distance formula, to get their length an add them up, and that's the perimeter of the polygon.

so, those are their lengths, sum them all up, that's the polygon's perimeter.
