Find the area of the shaded region

kodGreya [7K]

Answer: 21.994 cm²

Step-by-step explanation:

Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.

Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142

Now area of the bigger circle = 3.142 x 3²

= 3.142 x 9

= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2

= 6.284 cm².

Therefore are of the shaded region = 28.278 - 6.284

= 21.994 cm²

Answer:

The quotient is $x^2-3x+1$

Step-by-step explanation:

The given polynomial division is $(x^3-4x^2+4x-1)\div (x-1)$

To perform the synthetic division we write out the coefficients and arrange them as shown.

1 -4 4 -1

1 -3 1 0

The quotient is $x^2-3x+1$
