Question

The radius of a circle is 1. What is the length of an arc that subtends an angle of a radians?

Answer 1

1 unit

Explanation:

We have the following formula to find the length of an arc that subtends an angle of radians is:

S = rΘ where:

• r is the radius
• Θ is the subtended central angle given in radians

Given the information in this question, we have:

• r = 1 unit
• Θ = a radian

=> the length of an arc in this question is:

1*1 = 1 unit

Hope it will find you well
