Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations.
Answer:
The approximate volume is 
Step-by-step explanation:
we know that
The exact volume of the cylinder is
so
To find the approximate volume of the cylinder, substitute the term 
by the approximate value of 
and then multiply
so
Try this solution (note, this is not the shortest way):
1. if the given length is 'l' and the width is 'w', then according to the condition 4*l=w;
2. according to the condition the perimeter is 30 ft. Formula of the perimeter is P=2(l+w), then 2(l+w)=30;
3. if to substitute '4*l' instead of 'w', the formula of the perimeter (from item no. 2) will be as 2(4*l+l)=30 or 10*l=30 ⇒ l=3 ft. The length is 3 ft.!
4. if l=3 ft., then w=4*3=12 ft. The width is 12 ft.!
5. Area is
A=w*l; A=12*3=<u>36 ft²</u>
Answer:
Step-by-step explanation:
there is no solution:
6-2(3-2x) = -4(3-x)
6-6+4x= -12+4x
4x= -12+4x
0=-12
