A cone has a diameter of 18 units and a slant height of 15 units. Find the volume of the cone.​
Rasek [7]

Formula for volume:

πr^2(h/3)

Diameter divided by 2 is the radius

18/2 = 9

radius: 9 units

Use pythagorean theorem to find height

x^2 + 9^2 = 15^2

225 - 81 = 144

x^2 = 144

x = 12

height: 12 units

Plug these number in the volume formula.

Thus, it should be looking as:

π9^2(12/3) = 1017.88

Answer:

1017.88 units^3

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
AlekseyPX

Answer:

No Solution

Step-by-step explanation:

If you grouped like terms, you would get n+(-n)+5-10=1

Both <em>n's</em> would cancel each other out.

I hope this helps! (If it's wrong, then tell me, I'll try to find the correct answer...)

Answer:

188\sqrt{2}-8\sqrt{5} feet

Step-by-step explanation:

Well the perimeter is the sum of all sides that means

P= lenght + width + lenght + width

P=2(lenght + width)

so

P=2(2\sqrt{8}+3\sqrt{5}+45\sqrt{8}-7\sqrt{5} )\\\\P=2((2+45)\sqrt{8}+(3-7)\sqrt{5})\\\\P=2(47\sqrt{8}-4\sqrt{5})\\\\P=2(94\sqrt{2}-4\sqrt{5})\\\\P=188\sqrt{2}-8\sqrt{5}
