Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)
Answer:
Volume of the cone = 318.19 cubic cm
Step-by-step explanation:
Volume of a cone = 1/3πr²h
r is the radius = 4cm
h is the height = 19cm
Substitute into the formula
Volume of a cone = 1/3π(4)²(19)
Volume of a cone = 1/3* 3.14 * 16 * 19
Volume of a cone = 954.56/3
Volume of a cone = 318.19 cubic cm
