Idk for sure but that’s what I think
Answer:
SYNTAX ERROR
Step-by-step explanation:
See attached picture for the answer:
The volume of a rectangular prism (which the frame is, having a square base with height) is given by
![V=lwh](https://tex.z-dn.net/?f=V%3Dlwh)
, where l is length, w is width, and h is height. Since the width of a square is equivalent to its length, the square's dimensions will be 8 feet by 8 feet. So the volume of the frame is
![V=8ft*8ft*1ft=64ft^{3}](https://tex.z-dn.net/?f=V%3D8ft%2A8ft%2A1ft%3D64ft%5E%7B3%7D)
.
We need to know how many
![5ft^{3}](https://tex.z-dn.net/?f=5ft%5E%7B3%7D)
bags fit in a
![64ft^{3}](https://tex.z-dn.net/?f=64ft%5E%7B3%7D)
frame, so we can divide 64 by 5 to find how many times 5 fits in 64:
![\frac{64}{5}=12.8](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B5%7D%3D12.8)
. You can't buy 8 tenths of a bag, so you'll need to buy 13 bags to ensure that you have enough cement to fill the entire frame.
The equation for cuircumference is 2
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r
so your answer would be either ( 78 Pi ) for an exact answer
or for decimal form it would be ( 245.044 )
