Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

bagirrra123 [75]

Answer:

$27\pi \ cm^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=6\ cm$

substitute

$A=\pi (6)^{2}=36 \pi\ cm^{2}$

Remember that a central angle of $360\°$ subtends for the area of a complete circle

by proportion

Find the area of the circle for a central angle of $270\°$

$\frac{36 \pi}{360} \frac{\ cm^{2}}{degrees}=\frac{x}{270} \frac{\ cm^{2}}{degrees} \\ \\ x=270*36\pi /360\\ \\x=27\pi \ cm^{2}$

rusak2 [61]

Answer:

40 square inches.

Step-by-step explanation:

It is given that the new club sticker is in the shape of a triangle.

Height of triangle = 8 inches

Base of triangle = 10 inches

We need to find the area of sticker.

Area of triangle $=\dfrac{1}{2}\times base \times height$

Substitute base = 10 and height = 8 in the above formula.

Area of triangle $=\dfrac{1}{2}\times 10\times 8$

Area of triangle $=\dfrac{80}{2}$

Area of triangle $=40$

Therefore, the area of the club sticker is 40 square inches.
