A circle with radius of 2cm sits inside a circle with radius of 4cm What is the area of the shaded region

Klio2033 [76]

ANSWER

$12\pi \: {cm}^{2}$

EXPLANATION

We want to find the area of the shaded region.

We find the area of the smaller circle and subtract from the area of the larger circle.

Area of smaller circle is

$a = \pi \: \times 2^{2} = 4\pi$

Area of larger circle is

$A = \pi \: \times {4}^{2} = 16\pi$

The area of the shaded region is:

$16\pi - 4\pi = 12\pi$

Answer:

See explanation

Step-by-step explanation:

Depends on what you round the numbers to, but let's say you round 102.3 to the nearest hundred (100) and 4.7 to the nearest one (5). We can easily solve 100/5 and get the answer 20.

The denominator of a fraction in the simplest form is greater than the numerator by 1. If 4 is added to the numerator, and 3 is

Fantom [35]

Answer:

Step-by-step explanation:

Let the original fraction is: x/ x-1

And we have that:

4 is added to the numerator => new numerator is: x+4
3 is subtracted from the denominator => new denominator is: x -1-3 = x -4

the fraction itself is increased by 2 $\frac{1}{6}$

<=> $\frac{x}{x-1} *2\frac{1}{6}$ = $\frac{x+4}{x-4}$

<=> $7x^{2} -70x +24 = 0$

Solve for X then we substitue into the original fraction

Reflect the triangle in the mirror line.

vredina [299]

Answer:

I can't include a picture but it will be the same shape except it will be flipped over and will look a bit like differently angled packman with the back of the mouth apart the same distance, with the mouth "pointier" part of it one line away from the red line from the other side.... Oof sorry if this didn't help, I tried my best...

Step-by-step explanation:

From the "point" of the blue triangle, go diagonally SE 2 spaces. From there, draw a straight line to the right for 3 spaces. From there, draw upwards two spaces, and then connect those two lines into a triangle.
