A cylinder and a cone have the same diameter:8 inches. The height of the cylinder is 3 inches.The height of the cone is 18 inche

sesenic [268]

The volume of cone is double of the volume of cylinder.

Further explanation:

We have to find both volumes first to compare the volumes of both.

Volume of Cylinder:

Given

Diameter = d = 8 inches

$Radius=r=\frac{d}{2}=\frac{8}{2}=4\ inches$

Height of cylinder=h=3 inches

$V_{Cyl}=\pi r^2h\\=3.14*(4)^2*3\\=3.14*16*3\\=150.72\ in^3$

Volume of Cone:

Radius=r=4 inches

Height of cone= h= 18 inches

$V_{con}=\frac{1}{3}\pi r^2h\\=\frac{1}{3}*3.14*(4)^2*18\\=\frac{1}{3}*3.14*16*18\\=301.44\ in^3$

We can see that

$2V_{cyl}=V_{Con}$

The volume of cone is double of the volume of cylinder.

Factor 64 - P. (8 - x(8 - x) (8 + x (8 - x) (X + 8)(x-8)

Question:

Factor $64-x^2$

(8 - x)(8 - x)

(8 + x) (8 - x)

(X + 8)(x-8)

Answer:

Option B: $(8+x)(8-x)$ is the factor

Explanation:

Given that the expression is $64-x^2$

We need to find the factor of the given expression.

Let us rewrite the expression as $8^2-x^{2}$

Since the expression is of the form $a^2-b^2$ , let us use the identity $a^2-b^2=(a+b)(a-b)$

where a = 8 and b = x

Substituting the values in the identity, then the expression can be written as

$8^2-x^{2}=(8+x)(8-x)$

Thus, the factor of the expression is $(8+x)(8-x)$

Hence, Option B is the correct answer.

A company made 1,215 yards of copper wire. They want to wrap the same amount of wire on each three poles. How many yards of wire

o-na [289]

Answer:

405 yards

Step-by-step explanation:

Given that,

A company made 1,215 yards of copper wire.

They want to wrap the same amount of wire on each three poles.

3 poles = 1,215 yards of copper wire

1 pole = 405 yards of copper wire

So, each pole will require 405 yards of copper wire.
