Answer:
3/7
Step-by-step explanation:
Use Y2-Y1/X2-X1
So, 7+2/7+14=9/21
9/21 can be simplified so divide both by 3 which leaves you with 3/7
Answer:Division! :)
Step-by-step explanation:
A central angle:
α = 170°
d = 9.1 cm
r = 9.1 : 2 = 4.55 cm
Area of a sector:
A = r² π α / 360°
A = ( 4.55 )² · 3.14 · 170° / 360°
A = 30.7 cm²
12.5% 80-70=10 then divide 10\80 to get .125 , then multiply by 100 to get 12.5%
