-1400 + 800 - 350 = - 950 meters
The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2
<span>r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared </span>
<span>r = 12 " </span>
<span>area = 4 X pi X 12 X 12 = 576 pi" squared </span>
<span>ANSWER Area will be 4 times the original</span>
