An arc of length 30 m : l = 30 m.
r = 15 m, ∠ A = ?
Formula for the length of an arc is:
l = r π A / 180° ( where A is the central angle )
A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 °
This is very close to your result.
Answer:The number is 209.708
Step-by-step explanation:
Put the value in the arc length= 3 cm then you will get the answer.
Perimeter = add up the sides
P = 5 1/4 + 2 5/6 + 8 7/12
need to get a common denominator of 12
5 1/4*3/3 = 5 3/12
2 5/6*2/2 = 2 10/12
8 7/12
P = 5 3/12+ 2 10/12 + 8 7/12
P = (5+2+8)+(3+10+7)/12
P=15 (20/12)
P =15 + 1 8/12
P = 16 2/3 ft
