Answer: 1.75 cubic feet concrete is needed.
Step-by-step explanation:
Alright, lets get started.
The volume of the pillar is :
We have given the height is 5 feet.
We have given the diameter is 4 inches.
So the radius will be :
Converting inches into feet.
The radius will be :
So the volume of the cylinder will be :
So the volume of the cylinder will be :
As there are 4 pillars, so total volume will be :
So, total volume will be :
Hence 1.75 cubic feet concrete is needed. : Answer
Hope it will help :)
To find 20% of 950 you would set it up as a proportion. When doing percentages the prevent is always out of 100 so the first step would be 20/100. You are trying to find a number out of 950 so the second part would be ?/950. Now you want to cross multiply and divide. 20*950=19,000 then you divide it by 100 (your other number) 19,000/100=190. So 20% of 950 is 190.
I would say 90 but I could be wrong because if the tents edge is 30 feet and she walks at the edge twice it would be 60 but when she go back wouldn’t that be the same distance so 90.
Correct me if I’m wrong
The unknowns in this problem are A. The number of boys and the number of girls in the class.
We know there are 7 more girls than boys, but because we don't know how many boys there are, we don't know how many girls there are.
$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)
