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.
"A is smaller"
Answer:
Step-by-step explanation:
Distance travelled on graph = AB + BC + CD + DA
AB = CD = (3 +2) = 5
BC = AD = 2 –(-2) = 4
Distance on graph = 2 × 5 + 2 × 4 = 10 + 8 = 18 spaces = 18 blocks

Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).
To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
