The diameter of the spherical core of the baseball measures approximately 1.31 inches. What is the volume of the core baseball?

Step-by-step explanation: 3.14 x .65 x .65 = 3.24

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

do you mean add both of the equations together

because if you do the answer is 10x-5
