The solution for r in the given equation is r = √[(3x)/(pi h)(m)]

<h3>How to determine the solution of r in the equation?</h3>

The equation is given as:

m = (3x)/(pi r^(2)h)

Multiply both sides of the equation by (pi r^2h)

So, we have:

(pi r^(2)h) * m = (3x)/(pi r^(2)h) * (pi r^(2)h)

Evaluate the product in the above equation

So, we have:

(pi r^(2)h) * m = (3x)

Divide both sides of the equation by (pi h)(m)

So, we have:

(pi r^(2)h) * m/(pi h)(m) = (3x)/(pi h)(m)

Evaluate the quotient in the above equation

So, we have:

r^(2) = (3x)/(pi h)(m)

Take the square root of both sides in the above equation

So, we have:

√r^(2) = √[(3x)/(pi h)(m)]

Evaluate the square root of both sides in the above equation

So, we have:

r = √[(3x)/(pi h)(m)]

Hence, the solution for r in the given equation is r = √[(3x)/(pi h)(m)]

Answer:

61°

Step-by-step explanation:

Alright so the total amount of degrees in a 5-sided shape or pentagon is 540°. Since we have four of the five total angles, we can solve for the last one.

Sum of all the degrees of all five angles = 540°

The variable x is representing our last unknown degree.

90° + 107° + 144° + 138° + x° = 540°

Add up all the known degrees and solve for x.

479° + x° = 540°

Subtract 479 on both sides so that we can isolate x.

479° + x° - 479° = 540° - 479°

x° = 61°

So our final answer is 61°

For the figures that have rotational symmetry, list the angles of rotation less than 360 degrees. For figures without rotational
elixir [45]
Answer:
This shape has no rotational symmetry.

Explanation:
Shapes with rotational symmetry have the property of looking the same after being rotated a degree smaller than 360.

Although this shape in the image does have symmetry, it does not have rotational symmetry because there is no way for it to look the exact same after being rotated.

I hope this helps!

Mai has a rectangular poster. The poster is 1.6 meters long and 1.2 meters wide.
dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

On a bicycle trail, the city is painting arrows like the one shown below:
Oliga [24]

Answer:

128

Step-by-step explanation:

Split the shape into a triangle and a rectangle.

The base of the triangle is 12 cm.

The height of the triangle is the height of the whole shape minus the height of the rectangle, which is: 14-11=3.

We know that the formula for the area of a triangle is 0.5xbxh

Therefore, the area of the triangle is 0.5x12x3 = 18.

NOW, lets work out the area of the rectangle.

The formula for the area of the rectangle is bxh.

= 11*10

= 110.

Now you add the area of the triangle to the area of the rectangle

18+110.

= 128.
