PLEASE PLASE PLEASEEEE HELP!!!!!!! Find the area and perimeter!

Mathematics

If you look at one of the curves, you can see that it is the circumference of one-fourth of a circle. The center of the two circles are points B and D, therefore the radii are both 8 cm.

The perimeter of half the shape is one-fourth of a circle and there are two of the curves, so perimeter is 0.5 * C where C = 2pi*r

Perimeter = 0.5 * 2 * pi * 8 = 8pi

We can find the area of one of the non-shaded corners by taking the area of the square (8*8 = 64) and subtracting one-fourth of the circle. 

64 - (0.25 * pi * 8^2) = 64 - 16pi..

There are two of these corners so multiply by 2 = 128 - 32pi

Now 64 - (128 - 32pi) = Area of shaded region.

In the diagram of circle O, what is the measure of ABC
vaieri [72.5K]

Answer:

34°

Step-by-step explanation:

The angle formed by two tangents is equal to half the difference of the intercepted arcs.

The first intercepted arc, between points A and C, is 146°.  This leaves

360-146 = 214° for the second intercepted arc.

The difference between these two is

214-146 = 68°

Dividing this by 2,

68/2 = 34°

3. Which two expressions are equivalent for any value of y? *
-Dominant- [34]

Given:

The pair of expressions in the options.

To find:

The two expressions are equivalent for any value of y.

Solution:

Two expressions are equivalent for any value of y, iff they are equivalent.

3(3y+3)=3(3y)+3(3)

3(3y+3)=9y+9

Clearly, 3(3y+3) is not equivalent to 6y+6 or 9y+6. So, options A and B are incorrect.

9(y+3)=9(y)+9(3)

9(y+3)=9y+27

9(y+3)=27+9y

The expression 9(y+3) is not equivalent to 12+9y. So, option C is incorrect.

The expression 9(y+3) is equivalent to 27+9y.

Therefore, the correct option is D.
