Does Anybody know this? Find the area of the shaded sector
Sunny_sXe [5.5K]

Step-by-step explanation:

your teacher was very nice and warned you about the trap in the question.

so, really, what do we have to do ?

a full circle represents 360°.

the shaded sector is the full circle minus the white sector !

this is the same as directly calculating the shaded sector for 360-75 = 285°.

so, the area of a circle is

pi×r²

in our case

pi×20² = 400pi

the needed fraction of the whole circle is either

75/360, if we want to subtract it for the solution

or

285/360, if we want to calculate the solution directly.

both lead to the same result.

400pi×360/360 - 400pi×75/360 =

= 400pi × 285/360 = 10pi × 285/9 = 2850pi/9 =

= 316.6666666...pi ≈ 316.7pi

Solve for x. 24= -4(x-1)
Marina CMI [18]

Answer:24 = 24x

Step-by-step explanation:Cross multiply:

2 * 12 = x * 24

Simplifying

2 * 12 = x * 24

Multiply 2 * 12

24 = x * 24

Reorder the terms for easier multiplication:

24 = 24x

Solving

24 = 24x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-24x' to each side of the equation.

24 + -24x = 24x + -24x

Combine like terms: 24x + -24x = 0

24 + -24x = 0

Add '-24' to each side of the equation.

24 + -24 + -24x = 0 + -24

Combine like terms: 24 + -24 = 0

0 + -24x = 0 + -24

-24x = 0 + -24

Combine like terms: 0 + -24 = -24

-24x = -24

Divide each side by '-24'.

x = 1

Simplifying

x = 1
