Question

Find the arc length of the partial circle.

Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

Answer 1

Answer: 1.57

Step-by-step explanation:

A full circle of radius r has a circumference of 2pi*r which is the perimeter aka distance around the circle's edge.

We divide that by 4 to get the arc length of the quarter circle and we'd get to (2pi*r)/4 = 0.5pi*r

Plug in r = 1 and pi = 3.14

0.5*pi*r = 0.5*3.14*1 = 1.57
