Answer:

314 inches³

Step-by-step explanation:

The area of a cone is πr²h/3. We need to find the height and radius of the cone. The height is 12 inches. radius * 2 = diameter.

Radius * 2 = Diameter
/2                  /2

Radius  = 1/2* Diameter
Radius = 5 inches

We substitute it in:

3.14 * 5² * 12/3:

3.14*25*4

314 inches³

Answer:

Step-by-step explanation:

V of cone= \frac{1}{3} \pi r^2h

D= R^2

Pi= 3.14

5^2=25

25x12= 300

300x3.14= 942

942/3= 314in^{3}

The slope of the line is m=3/4. One point is (x, 2) and (3,-4)<br> Find X
Viktor [21]

Answer:

x is 11

Step-by-step explanation:

We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1)

Substitute the numbers into the equation

y--4=3/4(x-3)

simplify

y+4=3/4(x-3)

do the distributive property

y+4=3/4x-9/4

subtract 4 from both sides

y=3/4x-25/4

this is the equation of the line.

Since it says that (x,2) is a point in the equation, we can substitute it into the equation

2=3/4x-25/4

add 25/4 to both sides

33/4=3/4x

multiply by 4/3

11=x

we can double check by plugging (11,2) into the equation of the line.

2=3/4(11)-25/4

2=33/4-25/4

2=2

it works! :)

Hope this helps!
