The formula for the volume of a cone is (1/3)*pi)*r^3*h. Here, r = 2 units.
Thus, the volume of this particular cone is:
V = (1/3)(3.14)((2 units)^2*(9 units). Please do the math, and then round off your answer to 2 decimal places.
The solution of the linear equations will be (-2, 1).
<h3>What is the solution to the equation?</h3>
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equations are given below.
y = -(5/2)x - 4
y = (1/2)x + 2
The above equations are the equation of the line.
The lines are drawn on the graph. And the lines intersect at (-2, 1).
Thus, the solution of the linear equations will be (-2, 1).

Answer:
The equation of the line that passes through the point (2, -1) and has a slope of -3 will be:
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given
substituting m = -3 and the point (2, -1) in the slope-intercept form of the line equation
y = mx+b
-1 = -3(2)+b
-1 = -6 + b
b = -1 + 6
b = 5
Thus, the y-intercept form of the line equation is b = 5
now substituting b = 5 and m = -3 in the slope-intercept form of the line equation
y = mx+b
y = -3x + 5
Thus, the equation of the line that passes through the point (2, -1) and has a slope of -3 will be:
Answer: 18 units
Explanation:
Area = π r²
1017.9 = π r²
r² = 1017.9 ÷ π
r² = 324
r = √324
r = 18
===> Radius = 18 units
