4 is the base because the formula for a triangle is base times height divided by two, you would know that 8 times 4 would equal 32. When divided by 2 it would equal 16 which is the area. So 4 is the answer.
The range is just the distance between the biggest number
and the smallest one.
The biggest number on that list is 350 .
The smallest number on that list is 75 .
The range is from 75 to 350, or a distance of 275 .
Given:
P: (2,0,5)
L: (0,6,4)+t(7,-1,5)
and required plane, Π , passes through P and perpendicular to L.
The direction vector of L is V=<7,-1,5>.
For Π to be perpendicular to V, Π has V as the normal vector.
The equation of a plane with normal vector <7,-1,5> passing through a given point P(xp,yp,zp) is
7(x-xp)-1(y-yp)+5(z-zp)=0
Thus the equation of plane Π passing through P(2,0,5) is
7(x-2)-y+5(z-5)=0
or alternatively,
7x-y+5z = 14+25
7x-y+5z = 39
Answer:
if you want in terms of π, then 3π
if you want it without π, then 9.42
Step-by-step explanation:
plug into formula
3= diameter
c=πd
c=π*3
3π or
π=3.14
so 3.14*3, which is 9.42
