Answer:

Area of the shaded part is 3.14 square unit.

Step-by-step explanation:

Area of the shaded part = Area of large semicircle - (Area of two small semi circles)

Area of large semicircle with center O = $\frac{1}{2}(\pi r^2)$

= $\frac{1}{2}\pi (2)^{2}$

= 2π

Area of semicircle with center O' = $\frac{1}{2}\pi (1)^2$

= $\frac{\pi }{2}$

Area of semicircle with center O" = $\frac{\pi }{2}$

Now substitute these values in the formula,

Area of shaded part = $2\pi - (\frac{\pi }{2}+\frac{\pi }{2})$

= $\pi$

= 3.14 square unit

Area of the shaded part is 3.14 square unit.

Please, I need help ASAP! Which of the following shows the true solution to the logarithmic equation mc019-1.jpg

bekas [8.4K]

X = 1 is the correct answer.
Using the log properties, remember that Log(base2)2 = 1

3log(base2)2x = 3
divide both sides by 3
log(base 2)2x = 1
log(base2)2 = 1
1 * x = 1
x = 1
