Answer:
I have solved your problem
Step-by-step explanation:
Surface area of cylinder:
The formula is SA= 2πr² + 2πrh
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.
height is the diameter of 4 balls line-by line, so height is 60*4 = 240
Now, plugging into the formula, we get:
SA = 2πr²+2πrh
SA = 2π(30)²+ 2π(30)(240)
SA= 50, 868
Surface Area of rectangular prism:
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"
