The area of the shaded sector of a circle is 64 pie cm^2
Here we are given that there is a circle: whose radius is cm and the angle formed by two radius that is angle of the sector is .
The area of the sector of circle is basically the area of the arc of a circle.
The two combination of two radii forms the sector of a circle while the arc is in between these two radii.
Area of sector is given by:
.л
Substituting the given value in the formula of area of sector:
Area of sector is=
We get after solving,
Area of sector= pie cm^2
So from the given options, option 4 is correct.
Hence the area of the sector is 64 pie cm^2

A
the word 'of' means to multiply
0.45 × 80 = 36
Z and 113° are supplementary, they add to make up 180. So z + 113 = 180, z = 67°. x and 113° are equivelant, so 8x + 41 = 113, x = 9.
Answer:
A. 12 and 43
Step-by-step explanation:
Pythagorean theorem is given as =
Where, a and b are the two legs of the right triangle, while c is the hypotenuse/longest leg of the triangle.
In the figure given, the side of the largest square = the hypotenuse of the triangle = c
While the side of the other squares = a and b respectively, of the triangle.
Area of square = s², where s is the side length of the square.
Since we are given that the area of the largest square = 55, this is also equivalent to c² in the Pythagorean theorem.
The side length of the largest square = √55 ≈ 7.4 = c
Therefore, to determine the area of the other squares, check the options given if they add up to give 55.
Option A: 12 + 43 = 55
Option B: 14 + 40 = 54
Option C : 16 + 37 = 53.
The correct possible areas of the smaller squares would be A. 12 and 43.
