Answer:

(-6,1)

Step-by-step explanation:

-2x+6y=18

-4x-6y=18

Add the two equations together to eliminate y

-2x+6y=18

-4x-6y=18

--------------

-6x   = 36

Divide each side by -6

-6x/-6 = 36/-6

x = -6

Now we need to find y

-2x +6y = 18

-2(-6) +6y = 18

12 +6y = 18

Subtract 12 from each side

12-12 +6y = 18-12

6y = 6

Divide by 6 on each side

6y/6 = 6/6

y = 1

Container A is cylinder with a radius of 10 units and a height of 10 units. A right cone has been carved from its base and has a
sergij07 [2.7K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

Height = 10 units

Radius = 10 units

Volume = π × 10² × 10

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Height = 10 units

Base = 10 units

Volume = 1/3 × π × 10² × 10

Since the cone has been carved from the cylinder, the statement that derives the formula to find the volume of container B is

π × 10² × 10 - 1/3 × π × 10² × 10
