Find the area of the sector of a circle with radius 2 inches formed by a central angle of 4.3 radians: (in square inches)
aleksandr82 [10.1K]

Answer:

8.6 in²

Step-by-step explanation:

The area of the entire circle is A = πr², or A = π(2 in)².

This corresponds to a central angle of 2π radians, or 6.28 radians.

The area of the sector described above is just a certain fraction of that:

4.3 rad

-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²

6.28 rad

What is the justification for each step in the solution of the equation 3(2x + 7) - 4 = 53 - 3x?
DerKrebs [107]
Step 1 3(2x+7)-4=53-3x given
step 2 6x+21-4=53-3x expanding
step 3 6x+17=53-3x adding (21-4)
step 4 9x+17=53 adding 3x to both parts
step 5 9x=36 subtracting 17 from both sides
step 6 x=4 divding by 9
