Using the volume of the cone, it is found that:

Height and diameter are both 33.7 feet.

---------------------------

The volume of a cone with height h and diameter d is given by:

V = \frac{\pi d^2h}{12} = \frac{3.1415 d^2h}{12}

In this question:

  • Diameter and height equal, thus d = h.
  • Volume of 10,000 cubic feet, thus V = 10000

10000 = \frac{3.1415h^3}{12}

3.1415h^3 = 120000

h^3 = \frac{120000}{3.1415}

h^3 = 38197.19

h = \sqrt[3]{38197.19}

h = 33.7

Thus, both are 33.7 feet.

Which system is equivalent to
sammy [17]

<u>Answer:</u>

D) 6x^2 - 8y^2 = 50

-6x^2 - 2y^2 = 11

<u>Step-by-step explanation:</u>

We are given the following two expressions:

3x^2-4y^2=25

and

-6x^2-2y^2=11

Now if we look at the option D) 6x^2 - 8y^2 = 50&#10; and -6x^2 - 2y^2 = 11, we can observe that the earlier part in the given expression is just a simplification of 6x^2 - 8y^2 = 50.

6x^2 - 8y^2 = 50\\\\2(3x^2-4y^2) = 50\\\\3x^2-4y^2 = \frac{50}{2} \\\\3x^2-4y^2=25

and the later part -6x^2 - 2y^2 = 11 is already the same.

Therefore, the correct answer option is D)  6x^2 - 8y^2 = 50

-6x^2 - 2y^2 = 11.

A floor rug is rectangular in shape. The width of the rug is 2 ft less than its length. The perimeter of the rug is 36 ft.
Ganezh [65]

Answer

Perimeter of rectangle, P = 2L + 2W

P = 36ft

Width, W

Length, L = W + 2ft

Perimeter of rectangle, P = 2L + 2W

Given; P = 36ft

36ft = 2W + 2(W + 2ft)

36ft = 2W + 2W + 4ft

32ft = 4W

8ft = W

L = W + 2ft

L = 8ft + 2ft

L = 10ft
