Question

Please help me find the length of this arc
(There’s a picture)

Answer 1

9.16 which is rounded to the nearest tenth

Explanation:

We will use the formula to find arc length which is 2πr=x/360 where x is the central angle measure and r represents the radius. The work is shown below:

2πr=x/36

(2)(3.14)(7.9)=66.4/360

49.612=0.18444444

When we multiply the two numbers, we get 9.16 rounded to the nearest tenth.

Answer 2

9.16 (rounded)

Explanation:

I used the equation S = r∅ from Precalc to help me solve this.

Step 1: Conversion of 66.4° to radians

66.4 (π/180) ≈ 1.1589

Step 2: Plug in rad in equation

S = (7.9 cm)(1.1589)

S = 9.1553
