Vertices of the triangle:
<span>J (-2,1), K (4,3), and L (-2,-5) </span>
<span>Area of triangle: 18
or
</span>determinant=
<span>4,3,1 </span>
<span>-2,1,1 </span>
<span>-2,-5,1 </span>
<span>determinant= 4(1+5)-3(-2+2)+1(10+2) = 36 </span>
<span>A = determinant/2
</span>36/2=18
Notice that one side is vertical. Use that side as base.
<span>Area is 18.</span>
N=2.98+4.6
n=7.58
I think this is correct
Answer:
diameter = 4
Step-by-step explanation:
A=pi*r^2
12.566=pi*r^2
3.99988202979=r^2
r=1.99997050723
diameter = 2r
d=2(1.99997050723)
d=3.99994101446 =4
2:1/4=2* 4/1=2*4= 8 is the answer
a: b/c = a * c/b=a*c/b
