Question

Find the length of the bold arc. Round to the nearest tenth and use 3.14 or the pi button on your calculator for pi.

Answer 1

Answer:

8π yards

Step-by-step explanation:

A circle subtends a total angle of 360 ° from its center.The length of an arc is directly proportional to the angle it subtends from the circle's center. The arc's length can therefore be calculated as:

C=πd=2πr

Where C is circumference, d is diameter and r is radius. Given r as 16 yards then the arc length which is equivalent to circumference is given as

$C=\frac {90}{360}*2*\pi*16=8\pi$
