What is the volume of a sphere whose radius is 6 ft?

48π ft3

324π ft3

288π ft3

144π ft3

The volume of the sphere is option 3. 288π ft³.

Step-by-step explanation:

Step 1:

The given sphere has a radius of 6 ft.

The volume of a sphere is given by multiplying with π and the cube of the radius (r³).

The volume of a sphere,

Step 2:

Here the radius r is 6 inches. We take π as itself.

The volume of a full sphere,

ft³.

The volume of the sphere is 288π ft³, This is the third given option.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
