Answer:
The correct answer is option 1.
cubic units.
Step-by-step explanation:
The formula for the volume, V of a right angled cone is given as:

Where, 
is the radius of the circular base of the cone.
is the height of the cone.
We are given that height is twice of the radius of its base.
Let the radius of base =
units
Now, As per the question statement,
The height of cone=
units
Putting the values of
in equation (1) to find the volume:

Hence, the correct answer is option 1.
cubic units.
Answer:
The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.
The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.
The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:
No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).

Answer:
who is that ? :/
Step-by-step explanation:
Answer:
52 minutes
Step-by-step explanation:
it takes him 13 minutes to complete 5 so if he wants to do 20 problems do 20 divided by 5 (4) then do 13 times 4=52
