The diameter of the larger circle is 12.5 cm.
notsponge [240]
If the diameter of the smaller circle is 3.5cm, that means the radius is 1.75cm.The area of the smaller circle is π × 1.75², which is ≈ 9.62112750162. 
The diameter of the larger circle is 12.5 cm, so the radius would be half that, which is 6.25cm. The area of the larger circle would be π × 6.25², which is ≈ 122.718463031.
So now that we know the area of the larger circle and the smaller circle, we can find the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle, which is basically just 122.718463031 - 9.62112750162, which is = 113.097336. The closest answer here is 113.04, hence the answer is 113.04cm².

find the volume of a rectangular prism if the length is 3x^2, the width is 2xand the height is x^2+3x+5
nevsk [136]

You are given the length of a rectangular prism of 3x^2, width of 2x and height of x^2 + 3x +5. You are required to find the volume of a rectangular prism. Using the equation V = l x w x h, we multiply the three dimensions.

V = l x w x h

V = (3x^2)(2x)( x^2 + 3x +5)

V = 2x (3x^4 + 9x^3 + 15x^2)

V = 6x^5 + 18x^4 + 30x^3

The volume of the rectangular prism is 6x^5 + 18x^4 + 30x^3.

For each equation given below, write ONE related equation. a) x + 5 = 18 b) 66x =330
GenaCL600 [577]

Answer:

x = 13 ; x = 5

Step-by-step explanation:

The easiest related equation to get is simply solving for x:

a) x + 5 = 18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:

x + 5 (-5) = 18 (-5)

x = 18 - 5

x = 13*

b) 66x = 330

Isolate the variable, x. Divide 66 from both sides of the equation:

(66x)/66 = (330)/66

x = 330/66

x = 5*

*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.

You paint a border around the top of the walls in your room. What angle does X repeat the pattern? 154
Grace [21]

What does 154 mean in your question?

I assume your room is a square. If so, each corner of the room has a 90 degree angle for a total of 360 degrees.

The angle that is repeated, I assumed based on your obscure question, is 90 degrees.

So, x = 90 degrees.
