Find the arc length of a partial circle
2 answers:
Answer:
12.5664 units (rounded off to four decimal values)
Step-by-step explanation:
Arc length = 2 × π × r × 
For our partial circle;
The radius (r) = 8 units
The central angle = 90°
Arc length = 2 × π × 8 ×
= 12.5663706144 units
Or 12.5664 units (rounded off to four decimal values)
Answer:
4π units or 12.56 units
Step-by-step explanation:
We want to find the arc length of 1/4 of the circle.Let's start by finding the circumference of the circle.
Circumference of the circle= 2πr
2π*8
8*2π
=16π
We now want to find the arc of the 1/4 of the circle.
The arc length is 1/4 of the circumference of the circle.
1/4*16π
16/4π
=4π
The arc length of the partial circle is <u>4π units.</u>
Or 4*3.14=<u>12.56 units</u>
