# What is the arc length if theta is 7π/ 4, and the radius is 5?

**Solution:**

Arc length is the measure of the distance along the curved line making up the arc.

To find arc length, we can use the formula,

Arc length = θ × r

Where, r = radius, θ = angle in radian

Here r = 5 and θ = 7π/4

Arc length = (7π/4) × 5

= 35π / 4

= 8.75π

Therefore, the arc length is 8.75π

## What is the arc length if theta is 7π/ 4, and the radius is 5?

**Summary:**

The arc length if theta is 7π/ 4, and the radius is 5 is 8.75π.
