Have a nice day! ;)
Answer:
The answer is <u>C : a cylinder with a base radius of 9 inches</u>
Step-by-step explanation:
The area is 270² inches, and to find the area of a rectangle is width × length . So the equation would be 270 = W × L, which would convert to 270 = W × 15 and 15 times 18 equals 270. But that is not thew answer because you would need top find the radius of the cylinder which is half of the width of the rectangle which means the radius is 9. So the answer is a<u> cylinder with a base radius of 9 inches. </u>
Well, this depends on the size of the books. We can find the volume of the bin by using...
V=bh or l x w x h
So, 9 times 11 is 99.
99 times 4 is 396, which is the volume.
You did not specify the size of the books, so all we can say is that the volume of the bin is 396 cubic feet.
So you’d add 5 and 3 so it’s 8 ft/s
You then divide 220/8
So it should be 27.5 seconds.
Sorry about that other guy. Hope this helps!
