Answer: M=32°

Step-by-step explanation:

The identity sin²(x)+cos²(x)=1 can help us figure out the value of M. You can see that the problem's format fits exactly the identity. Since x is the same in the identity, we know that M=32°.

Answer:

216 $\pi$

Step-by-step explanation:

Given the figure.

And the perimeter in the ratio 4: 2: 1.

Perimeter of smallest circle = $8\pi$

To find:

Area of shaded region.

Solution:

To find the area, we need to have radius first.

And radius can be calculated by the given perimeter.

Formula for Perimeter is given as:

Perimeter = $2\pi r$

$8\pi = 2\pi r\\\Rightarrow r = 4\ cm$

Radius of smallest circle = 4 cm

Ratio of perimeter is equal to the ratio of the radii.

Radius of 2nd smallest circle by the given ratio = 8 cm

Radius of largest circle = 16 cm

Area of a circle is given the formula:

$A = \pi r^2$

Area of the smallest circle = $\pi 4^2 = 16\pi\ cm^2$

Area of the 2nd smallest circle = $\pi 8^2 = 64\pi\ cm^2$

Area of the largest circle = $\pi 16^2 = 256\pi\ cm^2$

Area of the shaded region = Area of largest circle + 2 $\times$ Area of 2nd smallest circle + 3 $\times$ Area of smallest circle - 2 $\times$ Area of smallest circle - 3 $\times$ Area of 2nd smallest circle
