Answer:D

Step-by-step explanation:

Radius=r=8

Φ=2π/3

π=180

2π=360

length of arc=Φ/360 x 2 x π x r

Length of arc=(2π/3 ➗ 2π) x 2 x π x 8

Length of arc=(2π/3 x 1/2π) x 2 x π x 8

Length of arc=((2πx1)/(3x2π)) x 2 x π x 8

Length of arc=2π/6π x 2 x π x 8

Length of arc=1/3 x 2 x π x 8

Length of arc=(1 x 2 x π x 8)/3

Length of arc=16π/3

Solve. 2(2z – 4) = 4

Oxana [17]

Answer:

$z = 3$

Step-by-step explanation:

1) Divide both sides by 2.

$2z - 4 = \frac{4}{2}$

2) Simplify 4/2 to 2.

$2z - 4 = 2$

3) Add 4 to both sides.

$2z = 2 + 4$

4) Simplify 2 + 4 to 6.

$2z = 6$

5) Divide both sides by 2.

$z = \frac{6}{2}$

6) Simplify 6/2 to 3.

$z = 3$

therefor, the answer is z = 3.
