What is the approximate area of the shaded sector in the circle shown below? A. 150.8 cm2 B. 6.28 cm2
C. 37.7 cm2
D. 3.14 cm2

C

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

(central angle is equal to the measure of the arc, that is 30° )

A = πr² ×

   = π × 12² ×

   = 144π ÷ 12

   = 12π

    ≈ 37.7 cm² ( to the nearest tenth )

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
