Answer:

V=1071.78\ cm^3

Step-by-step explanation:

Given that,

The radius of the cone, r = 8 cm

The height of the cone, h = 16 cm

We need to find the volume of the cone. The formula for the volume of the cone is given by :

V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 8^2\times 16\\\\V=1071.78\ cm^3

So, the volume of the cone is equal to 1071.78\ cm^3.

3 times a number is 54 less than the square of that number. Find the positive solution.
OlgaM077 [116]

Answer:x=9

Step-by-step explanation:

To find the positive solution for this, then we will say;

Let the number be x

3x<x^2-54

x^2-3x-54<0

Then we are going to factorise

x^2-9x+6x-54=0

(x^2-9x)+(6x-54)=0

x(x-9)+6(x-9)=0

(x+6)(x-9)=0

Therefore, The positive solution for this is: x=9

Find the side of a square whose diagonal measures 15 square root of 2
solmaris [256]

Answer:  15 units .

__________________________________________________

In this case, a square, the two sides of the square (forming a right triangle) are equal), and the "diagonal" forming is the hypotenuse of the right triangle.

In these cases, the measurements of the angles of the right triangle are "45, 45, 90" ; and the measurements of the sides are:  "a, a, a√2" ; in which "a√2" is the hypotenuse.

We are given:  "15√2" is the hypotenuse" ; and we are given that this is a right triangle of a square with a diagonal length (i.e. "hypotenuse" of "15√2" ; so the measure of the side of the "square" (and other two sides of the triangle formed) is:  15 units.   (i.e.,  15, 15, 15√2 ).

Answer:

π(5²)(13)+⅓π(5²)(12)

Step-by-step explanation:

You can find the volume of the cylinder by:

V=πr²h

which is V1=π(5²)(13)

and the volume of the crooked cone by:

⅓πr²h

which is V2=⅓π(5²)(12)

and you need the volume of the whole shape. you can find by adding V1+V2
