Answer:
The first one shows 25%
In the 1st modal, a whole is divided into 4 and 1 of the 4 is selected or highlighted
And as the whole rectangle is 100% and being divided into four its becomes 100/4% and when we solve we get 100/4=25
And thus its the first modal that shows 25%
In the second case its divide into 3 boxes so.. 100/3% and when we solve we get 33.3333333.......and this is not what we want
THEREFORE, THE CORRECT ANSWER IS 1ST MODAL
To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8
the area is 48 square units, the perimeter is 12π+8 units.
Answer:
AABC and AXYZ are similar triangles. The lengths of two sides of each triangle are shown. Find the lengths of the third side of each triangle
I hope this helps you
Area=pi.r^2
r^2=Area/pi
r= square root of Area/pi
1) it must be fulfilled that the denominator is different from zero, then for this expression
x^2 -9 ⇒ x^2-3^2 = (x-3)(x+3)⇒ (x-3)(x+3) = 0 ⇒ x = 3 o x = -3 , the dominium is all numbers reals except 3 and -3
