Find the volume of a right circular cone that has a height of 18.9 in and a base with a

Answer:

The volume of the cone is:

  • <u>112.6 cubic inches.</u>

Step-by-step explanation:

You should know that the volume of a straight circular cone is equal to:

  • Cone volume = (1/3) PI * r ^ 2 * h

Where:

<em>r = radius. </em>

<em>h = height. </em>

Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:

  • Circumference = PI * Diameter.

When clearing you get:

  • Diameter = circumference / PI

By replacing the data you get:

  • Diameter = 15 inches / PI
  • Diameter = 4.77 inches.

Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:

  • Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in
  • Cone volume = 112.581541 in^3
  • <u>Cone volume = 112.6 in^3</u>

What is the value of X?
Leviafan [203]

Answer:

w = 31

Step-by-step explanation:

To find the value of w:

 We know that the three angles in a triangle add to 180 degrees

w + w + (4w-6) =180

Add like terms

6w-6 = 180

Add 6 to each side

6w -6+6 =180+6

6w = 186

Divide each side by 6

6w/6 = 186/6

w = 31

I need major help pls help

Answer:

No, since 832 ≠ 900, using Pythagorean theorem, the width should be 18 in

Step-by-step explanation:

It is better to type the question in the 'Question' than the fact that you need help so that we can start seeing the problem immediately.

A rectangle has 4 right angles so if l = 24 and w = 16 then you can use the pythagorean theorem to see if this is possible since

24^2 + 16^2 = 30^2 since the diagonal is the hypotenuse of the triangles formed by the diagonal in the rectangle.  

576 + 256 ≠ 900, since the left side is 832 and the right side is 900

It would be more correct if the width is 18 since 576 + 18^2 = 900
