Answer:
The subtraction method is used to find the volume of the cylinder by recalling that the volume of the cylinder consist of the volume of the cone and the volume of the sphere.
Step-by-step explanation:
In the subtraction method, we have that a cylinder of radius r, equal to that of a circle, and height 2·r consist of a cone of base radius r and height 2·r and a sphere of radius r as follows;
Volume or sphere of radius r = Volume of cylinder of radius r and height 2·r - Volume of cone of base radius r and height 2·r
∴ 4/3·π·r³ = Volume of cylinder of radius r and height 2·r - 2/3·π·r³
Hence, volume of cylinder of radius r and height 2·r = 4/3·π·r³ + 2/3·π·r³ = 2·π·r³
Hence the subtraction method is used to find the volume of the cylinder by recalling that the volume of the cylinder consist of the volume of the cone and the volume of the sphere.
Answer:
X/2 = 61.2
X=122.4
Step-by-step explanation:
Ok so we know that a number was halved so we can use x and equaled to 61.2 so we can do x/2 = 61.2

Answer:
X = 10
Step-by-step explanation:
The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.
Then all you have to do is solve for the equation.
2x + 30 = 5x
Subtract 2x from each side
30 = 3x
Divide by 3
10 = x
The baker needs to sell 10 muffins in a day to make enough to cover the revenue.
