a circle with radious of 1cm sits inside a 11cm times 12 cm rectangle what is the area of the shaded region
Nitella [24]

Answer: 128.86cm²

Step-by-step explanation:

The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.

Area of the rectangle                                  =  11 x 12

                                                                     =  132cm²

Area of the circle with radius of 1cm          =  πr²

                                                                     = 3.142 x 1²

                                                                     = 3.142cm²

Therefore , area of the shaded  region      = 132cm²  -  3.142cm²

                                                                    = 128.86cm²

Solve the system of linear equations by substitution
ziro4ka [17]

y - x = 0  ...equation 1
2x - 5y = 9 \: ...equation  \: 2
working with equation 1
y = x \: ...equation \:  3
next subsitue equation 3 in equation 1
2x - 5(x) = 9
2x - 5x = 9
- 3x = 9
divide by -3
x =  - 3
substitute x= -3 in equation 1
y - ( - 3) = 0
-(-3) = + 3
y =  - 3

Math is annoying! Can someone help me please?
lord [1]
16.  would be C since they both consist of the same variable to the same power

17. x-2x+7-9+4x
     c. 3x-2
18. -4(3a-5). You would multiply -4 by 3 a, and -4 by -5. It turns to
      -4(3a)-4(-5)
     a. -12a+20
