80/20=4. 4x4=16. 16 weeks for an 80 wall painting
50 x 32 = 1600square feet
area of a square is S^2 so the length of the side of a square would be 1600 =S^2
S=sqrt(1600) = 40 feet long
perimeter of a square is 40 x 4 = 160 feet
To write the problem out as an equation, let 'n' equal your number.
(15 x 1/n) - 3n
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475
Answer:
