Answer:
Volume of a cone = 847.8 cm³
Step-by-step explanation:
Volume of a cone = 1/3hπr²
π = 3.14
radius, r = 9 cm
height, h = 10 cm
Volume of a cone = 1/3hπr²
= 1/3 * 10 * 3.14 * 9²
= (1 * 10 * 3.14 * 81) / 3
= 2543.4 / 3
= 847.8
Volume of a cone = 847.8 cm³
In this situation you would add 9 to the other side of the inequality 2/5x < 9/10+9
2/5x< 9.9
