Can anyone help me with this please!!
Levart [38]

Answer:

22.88 cm^3

Step-by-step explanation:

The volume of a sphere formula is (4/3)*pi * (radius)^3

Since the diameter is 5.08cm, we divide by 2 to find the radius which is 2.54 cm.

Also because of the fact that 2/3 is showing outside the cone, that means 1/3 is inside the cone. Therefore, we have to multiply the volume by 1/3.

We have:

Volume = (4/3) * pi * (2.54)^3 * (1/3)

= 22.88 cm^3

Whats the answer for (5x + 8)(4x² + 6x - 8)
mestny [16]
(5x + 8)(4x^2 + 6x - 8)\\ \\ 5x(4x^2 + 6x - 8) + 8(4x^2 + 6x - 8) \\ \\ 20x^3 + 30x^2 - 40x + 8(4x^2 + 6x - 8) \\ \\ 20x^3 + 30x^2 - 40x + 32x^2 + 48x - 64 \\ \\ 20x^3 + (30x^2 + 32x^2) + (-40x + 48x) - 64 \\ \\ 20x^3 + 62x^2 + 8x - 64 \\ \\

The final result is: 20x^3 + 62x^2 + 8x - 64.
