\frac{Angle}{360} x 2 \pi r

\frac{125}{360} x 2 \pi (10) = 21.82

Answer:

21.82\ ft

Step-by-step explanation:

we know that

The circumference of a complete circle is equal to

C=2\pi r

In this problem we have

r=10\ ft

substitute

C=2\pi (10)=20 \pi\ ft

Remember that

An angle of 360\° subtends the arc length of a complete circle

so

by proportion

Find the arc length for an angle of 125\°

\frac{20 \pi}{360}\frac{feet}{degrees}=\frac{x}{125}\frac{feet}{degrees}\\ \\x=125*(20\pi )/360\\ \\x=21.82\ ft

Find the percentage error |sinθ - θ|/sin(θ)*100 this approximation introduces for an angle of 0. 020 radians.
Elza [17]

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

<h3>What is the percentage angle for an angle?</h3>

For an angle \theta, it is given by the following formula:

P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}

In this problem, the angle is of \theta = 0.02, hence:

P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}

P = 0.0067

The percentage error for an angle of 0.02 radians is of 0.0067%.
