Answer:
Step-by-step explanation:
3*7*10*10*10*10*10*10*10
(5+2=7)(since is multiplication you add)
21*
=B
<u>2*10*10*10*10*10</u>
4*10*10
(5-2=3)(since is division you subtract)
0.5*
=c
Take 0.53 and 0.7 by 100 to make them percents. 0.53 times 100 is 53% and 0.7 time 100 is 70%. so 0.7>0.53
Answer: There are 13464 cubic feet in the lake.
Step-by-step explanation:
Since we have given that
Surface area of lake = 748 acres
Average depth of lake = 18 feet
So, Volume of lake would be
Surface area of lake × Average depth

Hence, there are 13464 cubic feet in the lake.
