Answer:

Step-by-step explanation:

According to the ratios table, if

sin theta = 1/2

Then theta = 30°

Cos theta = cos 30° =root 3 /2

Step-by-step explanation:

\because \sin \theta =  \frac{1}{2}  \\   \therefore \sin \theta =  \sin 30\degree \\   \\ \huge \red{ \boxed{ \therefore  \theta = 30\degree }} \\  \\  \cos \theta =  \cos 30\degree  \\  \huge \purple{ \boxed{\therefore \cos \theta =   \frac{ \sqrt{3} }{2} }} \\

The diagram above shows a rectangle inscribed in a circle AB=10 and AC =12 caculate the total surface area of the shaded part
erastova [34]

Answer:

71.63 \: \: \mathrm{cm^2 }

Step-by-step explanation:

Once we know the diameter of the circle, we can figure out the problem.

The diameter of the circle = The diagonal of the rectangle inscribed in the circle

To find the diagonal of the rectangle, we can use a formula.

d=\sqrt{w^2 + l^2}

The width is 10 cm and the length is 12 cm.

d=\sqrt{10^2 + 12^2}

d \approx 15.62

The diagonal of the rectangle inscribed in the circle is 15.62 cm.

The diameter of the circle is 15.62 cm.

Find the area of the whole circle.

A=\pi r^2

The r is the radius of the circle, to find radius from diameter we can divide the value by 2.

r = \frac{d}{2}

r=\frac{15.62}{2}

r=7.81

Let’s find the area now.

A=\pi (7.81)^2

A \approx 191.625

Find the area of rectangle.

A=lw

Length × Width.

A = 12 \times 10

A=120

Subtract the area of the whole circle with the area of rectangle to find area of shaded part.

191.625-120

71.625 \approx 71.63
