Does anyone know the volume?

2048π/3

or 2144.6606

Step-by-step explanation:

The formula to find the volume of a sphere is

V=4/3πr^3

To find the solution, plug in the value of the radius, 8

V=4/3 * π * (8^3)

Then solve by combining 4/3 and π to get, 4π/3 and raise 8 to the power of 3 to get 512. You would then get

4π/3 * 512

Multiply that to find the solution of

2048π/3

or 2144.6606

2

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
