Answer:

h = 3x^5-3x^2-10\text{ units}

Step-by-step explanation:

We are given the following in the question:

Volume of cylinder =

V=Bh

where B is the area of base and h is the height of cylinder.

Volume of cylinder =

V = 6\pi x^7-6\pi x^4-20\pi x^2

Base area =

B = 2\pi x^2

We have to find height of cylinder.

h = \dfrac{V}{B}\\\\h = \dfrac{6\pi x^7-6\pi x^4-20\pi x^2}{2\pi x^2}\\\\h = 3x^5-3x^2-10\text{ units}

Thus, the height of cylinder is 3x^5-3x^2-10 units.

Answer:

h=3x^5-3x^2-10

Step-by-step explanation:

We have been given that volume of a certain cylinder is 6\pi x^7-6\pi x^4-20\pi x^2 and base area is 2\pi x^2. We are asked to find the height of the cylinder.

We know that a cylinder's volume can be calculated by the formula V=Bh, where V stands for volume, B stands for base area, and h stands for height.

Let us solve for h.

h=\frac{V}{B}

Upon substituting our given values, we will get:

h=\frac{6\pi x^7-6\pi x^4-20\pi x^2}{2\pi x^2}

Let us factor out 2\pi x^2 from numerator.

h=\frac{2\pi x^2(3x^5-3x^2-10)}{2\pi x^2}

Upon cancelling out same terms, we will get:

h=3x^5-3x^2-10

Therefore, the height of the cylinder would be 3x^5-3x^2-10 units.

Two sides of a triangle are equal in length and double the length of the shortest side . The perimeter of the triangle is 36 inc
Firdavs [7]

Answer:

The length of the sides of the triangle are as follow: Two sides are 14.4 inches long and the shortest is 7.2 inches.

Step-by-step explanation:

P = 36in // perimeter of triangle

P = A + B + C //equation for perimeter of a triangle

A = B or B = A //Showing that two sides are equal in length

A = 2C and B = 2C //Showing that the two equal sides are each doubled of the shortest side

C = A/2 and C = B/2 //Showing the same thing as the top, but in terms of the shortest side

Solve for C //First we solve for the shortest side as it's easiest

36 = A + B + C

36 = 2C + 2C + C //Use substitution for A and B

36 = 5C

C = 7.2in

Solve for A

A = 2C

A = 2(7.2) //Use what we solved for C

A = 14.4in

Solve for B

B = A

B = 14.4in //Same as A

Check Work

P = A + B + C

P = 14.4 + 14.4 + 7.2

P = 36
