Find the volume of the cylinder. use 3.14 for pi.

The correct answer is first option. 52.8 m³

Step-by-step explanation:

Formula:

Volume of cylinder = πr²h

r - Radius of cylinder

h - Height of cylinder

From the figure we can see that,

Radius r = 2 m and height h = 5 m

To find the volume of cylinder

π = 3.14

Volume =  πr²h = 3.14 * 2² * 5 = 3.14 * 4 * 4 * 5 = 3.14 * 20 = 62.5 m³

Therefore volume of cylinder = 62.5 m³

First option is the correct answer

- 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
