Answer: dowel is 24.5 long
Step-by-step explanation:
If Lana cuts 2 pieces of every 7 inches from dowel that means each piece is of 3.5 inches, and she needs total 7 pieces for a project so;
3.5*7=24.5
Answer:
The lines will intersect 595 times.
Step-by-step explanation:
We can do it in 2 methods.
<u>1st method:-</u> Let us count the number of intersections by drawing lines one by one.
1st line - 0 points=0
2nd line- new 1 point=1
3rd line - old 1 point + new 2 points with two old lines = 1+2
4th line - old (1+2) points+ new 3 points= 1+2+3
5th line - old (1+2+3) points + new 4 points=1+2+3+4
Like that from 35th line-1+2+3+4......34 = 
<u>2nd method:-</u>
We have to choose 2 lines from 35 lines.
We can do it in
ways = 595 points

Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders
