Answer:
48,558
Step-by-step explanation:
The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:
Now, 2020-2010=10 Years
Therefore we are required to calculate the population of the town 10 years after.
To do this, we simply substitute t=10 in the function.
According to the model, the population in Fall River will be 48,558 in the Year 2020.
Answer:
"A is smaller"
Step-by-step explanation:
The full question is attached.
<u>Surface area of cylinder:</u>
The formula is
where r is the radius and h is the height
Here, radius would be 30 since balls have diameter 60 and radius is half of that.
Also height is the diameter of 4 balls line-by-line, so height is 60*4 = 240
Now, plugging into the formula, we get:
<u>Surface Area of rectangular prism:</u>
The surface area of rectangular prism is the area of all the rectangular surfaces (6 of them).
Area of top and bottom = (60+60)*(60+60) * 2 = 120*120 * 2 = 28,800
Area of 2 sides = 2 * (60*120) = 14,400
Area of front and back = 2 * (60*120) = 14,400
Total Surface Area = 28,800 + 14,400 + 14,400 = 57,600
Thus, cylinder has smaller surface area.
