Please help with this<br><br> Find the area of the shaded regions.
Mice21 [21]

Answer:

The area of the shaded region is 7π square centimeters.

Step-by-step explanation:

Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.

The area of a circle is given by:

\displaystyle A = \pi r^2

Therefore, the area of Circle B, the entire circle, is:

\displaystyle \begin{aligned} A_B &= \pi (3)^2  \\ &= 9\pi \end{aligned}

The area of Circle O is:

\displaystyle \begin{aligned} A_O &= \pi (1)^2 \\ &= \pi \end{aligned}

And likewise, the area of Circle C is:

\displaystyle \begin{aligned} A_C &= \pi (1)^2 \\ &= \pi \end{aligned}

The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:

\displaystyle A_\text{shaded} =A_B - \left(A_ O + A_ C\right)

Substitute and evaluate:

\displaystyle \begin{aligned} A_\text{shaded} &= (9\pi ) - (\pi + \pi) \\ &= 9\pi - 2\pi \\\ &= 7\pi \end{aligned}

The area of the shaded region is 7π square centimeters.

plssssssssssssssssssssss help Six friends, four boys and two girls, went to a movie theater. They wanted to sit in a way so no g
Airida [17]

Answer:

672 ways

Step-by-step explanation:

The total number of ways the friends were supposed to sit without restrictions would have been = 6!

= 720 possible ways.

If the girs should sit on the first or last sit

The possible arrangement= 2!4!

= 2*24

= 48

But now the two girls should be arranged in such a way that the don't sit on either the first or the last chair.

So the possible way now is= way without restriction - way if the girls are to sit at either first or last sit

= 720-48

= 672
