If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter, what is the volume of the tank? Assume 3.14 for pi.
Answers
Volume of a cylinder = cross sectional area * height so... height = 3m cross sectional area = pi × radius^2 radius = 1/2 diameter radius = 1/2 × 6 = 3 3.14 × 3^2 = 3.14 × 9 = 28.26 therefore... volume of cylinder = 28.26 × 3 = 84.78 m^3
volume = area of base x height v=pi x radius^2 x height
v=3.14 x 3^2(6/2 because 6 is diameter so must divide by 2 for radius) x 3 v=84.78 m3
kalil’s monthly salary is 3,250 plus he earns 1.4% commission on his sales for the month. Kalil’s sales for July were $51000. What was his total earning for July?
Answers
You add the Kalil's monthly salary (3,250) to his sales (51,000), then multiply 1.4% ( as a percent: 0.014) The equation for this problem is 3,250 + 51,000 (0.014) 54,250 (0.014) 3,964
3/4 w = 6 plz show your work 1.6y = 9 plz show your work
9.82 / 0.2 show work plz
9 9/10 /4 4/5 show work plz
Answers
Multiply by 5 × 5 = 6 × 5 3w = 30 Divide by 3
3 and 3 cancels out w = 10
1.6y = 9 Divide by 1.6
y = 5.625
0.2 | 9.82 0.2 × 10 = 2 9.82 × 10 = 98.2
49.1 2 | 98.2 -8 18 -18 0 2 -2 0 Which also gives us the same answer with decimals.

Change them to decimals, which makes it easier to divide
