The radius of a circle is 3 centimeters. What is the length of a 180° arc? Give the exact answer in the simplest form.

9.42 cm

Step-by-step explanation:

3.14*3=9.42

9.42*2=18.42

18.42/2=9.42

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
