6x9 + 3^2pi would be the area so 54+9pi=57.14
Step-by-step explanation:
We need to find the height of the triangle first.
Height=>sin(60°)=h/3 but sin(60°)=√3/2
h=3×√3/2=3√3/2
Area=½×base×height
A=½×3×3√3/2
A=9√3/4
Answer is option A
Answer:
96
Step-by-step explanation:
81+15=96
Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16
Answer:
rational, irrational is like pi or \sqrt{-7}
