Answer:

The voume of the cylinder is (pi)(x^2)(y)

Voulne of the cone is (1/3)(pi)(3x)^2(h). H is the unknown height of the con2

Since the volumes are equal

(pi)(x^2)y = (1/3)(pi)(9x^2)h

h= y/3

Answer:

575.4 sq inches

Step-by-step explanation:

you can divide this shape into:

13 x 13 square

trapezoid with bases of 13 and 30 with a height of 20

semi-circle with radius of 15

A(square) = 169

A(trapezoid) = 53

A(semi-circle) = 353.4

Step-by-step explanation:

Since $x$ varies directly as $\sqrt{y}$ we can write the relation as

$x = k\sqrt{y}$

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

$5 = k\sqrt{13} = k(13)$

$\Rightarrow k = \dfrac{5}{13}$

b) The equation relation x and y can be written as

$x = \dfrac{5}{13}\sqrt{y}$

c) When y = 9,

$x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}$

Answer:

The short answer is : x=6.81

Step-by-step explanation:

First thing to do is multiply in $\sqrt{2}$

<h3>To Until it become :</h3>

$5x {} ^{2} =164 * \sqrt {2}$

Now we will divided on 5 and calculate the numper to it equal 46.3

Then you will take square root To the two parties

To equal in the end =6.81
