Answer:
The volume of the cone is 128π mm³ ⇒ answer (C)
Step-by-step explanation:
* Lets study the cone
- Its base is a circle
- Its height the perpendicular distance from its vertex to
the center of the base
- The length of its slant height = √(h² + r²)
- The volume of the con is 1/3 the volume of the cylinder
∵ The volume of the cylinder = πr²h
∴ The volume of the cone = (1/3) πr²h
* In our problem:
- r = 4 mm
- h = 24 mm
∴ Its volume = (1/3) × π × (4)² × 24 = 128π mm³
* The volume of the cone is 128π mm³
The current time would be 3:15
Answer: it’s C.) X= 2
Step-by-step explanation:
For this case we have the following expression:
10x + 2
There are many different ways to describe the expression.
We will name some of these ways:
1) The expression is a linear function
2) The slope of the line is positive and equal to 10.
3) The cut point of the line with the y axis is 2.
4) The domain of the function is from -inf to inf.
5) The range of the function is from -inf to inf.
Answer: y = -1x + 8
Step-by-step explanation: linear equations must be written in the format
y = mx + b from.
m represents the slope which it -1
b represents the y-intercept which is 8.
Just substitute the slope and y-intercept in the m and b places and that is a linear equation.
