What is the volume of a cone with a diameter of 30 feet and a height of 60 feet? Use 3.14 for π.
AysviL [449]

Answer:

14130 ft^3

Step-by-step explanation:

The formula for the volume of a cone of radius r and height h is

V = (1/3)*pi*r^2*h.

Here, V = (1/3)(3.14)(15 ft)^2*(60 ft) = 20*3.14*225 ft^3 = 14130 ft^3

What is the the y-intercept and x-intercept of the line.<br> 4x - 4y= 36
algol13

Answer:

x-intercept: (9,0)

y-intercept: (0,-9)  

Step-by-step explanation:

The x-intercept and y-intercept is the point at which a line intersects the x-axis and y-axis, respectively. All points on the x-axis have a y-value of 0, while all points on the y-axis have an x-value of 0. Thus, to find the x and y intercepts, substitute 0 for one of the variables in the equation, then solve for the other.

1) To find the x-intercept, substitute 0 for y. Then, isolate x.

4x-4(0)=36\\4x-0=36\\4x = 36\\x = 9

So, the x-intercept must be (9,0).

2) To find the y-intercept, substitute 0 for x. Then, isolate y.

4(0)-4y = 36\\0-4y = 36\\-4y = 36\\y = -9

So, the y-intercept must be (0,-9).

What is the slope of the line graphed below (3,5) (0,-1)
Leona [35]
You can just do rise over run to find the slope or use the slope equation which is
y = y1 - y2 \div x1 - x2
3=x1
0=x2
5=y1
-1=y2
input those and you can get the slope graphed.
