a circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle, what is the area of the shaded region

mojhsa [17]

Answer:

42.43 $cm^{2}$

Step-by-step explanation:

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

$Area\ of\ cirle=\pi r^{2}$

$= =\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571$

As here length an width both are 11 cm, we can say that this is a square.

$Area\ of\ square=(Side)^{2}$

= $=11\times11=121\ cm^{2}$

Now, area of shaded region = Area of square - Area of circle

= 121 - 78.571 = 42.429 $cm^{2}$

Therefore, the area of the shaded region will be 42.43 $cm^{2}$

A19 = -58, a21 = -164

Marrrta [24]

I took a19=-58 divide it by 19 both side i get a = -58÷19 (note; you can never have a neg. # on the top bring the neg. down to the bottom and divide) now its 58÷-19= -3.05 or -3 (1÷19) so a = -3(1/19) do the same to the other now. answer is a=-7 (17/21)

Loe's walkie-talkie is at 20% when fully charged the battery lasts 12 hours Leo thinks the walkie-talkie will last his entire 3

katen-ka-za [31]

False because it will only last 2.4 hours. 12 x 20% = 2.4. Hope I could help! :)
