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 :)
5+4v-v=1+3+5v
5+3v=4+5v
minus 3v both sides
5+3v-3v=4+5v-3v
5+0=4+2v
5=4+2v
minus 4 both sides
5-4=4-4+2v
1=0+2v
1=2v
divide both sides by 2
1/2=v
Answer:
1.) 5
2.) 14
Step-by-step explanation:
As given,
the expression - 3x + 2
1.)
Evaluate the expression when x is 1
⇒ 3x + 2 = 3(1) + 2 = 3+2 = 5
2.)
Evaluate the expression when x is 4
⇒ 3x + 2 = 3(4) + 2 = 12+2 = 14
The answer is 16
2.04 divided by 6 is .34 which is how much each can cost
so if you take 5.44 divided by .34 it equals 16
