The volume of the solid is which is a cone is 100.48 
.
Given a cone of radius 4 km and height being 6 km.
We are told to find the volume of the cone.
Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.
Volume of cone is 1/3 
.
Volume =1/3 
=1/3 π*16*6
=32π
=32*3.14
=100.48
Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48.

Answer: OPTION D.
Step-by-step explanation:
For this exercise it is important to remember that:
1. Direct proportion equations have the following form:
Where "k" is the constant of proportionality.
2. The graph of Direct proportions is an straight line that passes through the origin.
Observe the picture attached.
If you join the points G, C and A, you get a straight line that passes through the origin,
If you join the points F, G and H, you also get a straight line that passes through the origin,
Therefore, the sets of points show "x" in Direct proportion to "y", are:
and 
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed
T=2n+3
considering n has no other values given
