S=180(7)
S=1260
Answer:
210 m
Step-by-step explanation:
the largest interior angle will be the front of largest side of triangle
Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
452.39 cm is the correct answer
Answer:
r = 45 m.
Step-by-step explanation:
pi r^2 = 6358.5
r^2 = 6358.5 / pi
r = √(6358.5 / pi)
= 44.989 m
