Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
Answer:
21
Step-by-step explanation:
42% of 42 is 84% of what number
Let the number be y
42% of 42 is 84% of y
NOTE: Of means multiplication
42/100 × 42 = 84 /100 × y
1764/100 = 84y/100
cross multiply over the equal sign
176400 = 8400y
divide by 8400
176400/8400 = 8400y/8400
y = 21
To verify
42% of 42 is 84% of a number
42% of 42 is 84% of y
42/100 × 42 = 84/100 × 21
1764/100 = 1764/100
17.64 = 17.64
Answer:
40
Step-by-step explanation:

.5 x 80
40 units^2
How can you determine the best method of solving a system of equations?
Elimination is best used when both equations are in standard form (Ax + By = C).
Elimination is also the best method to use if all of the variables have a coefficient other than 1.
