It would cost about $4.86!
A hemisphere. The formula for a hemisphere is V = (2 / 3)πr^3<span>. r is the radius. if you are given a radius, plug it into the formula to find the answer if a radius is given. </span>
First, all the heights have to be converted to similar units, say feet.
Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet
The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).
When it is in motion the force is unbalanced. When it stops the forces are balanced.
Answer:
400cm^2
Step-by-step explanation
equation: a+b/2 x h
19+25/2 x 20
44/2 x 20
22 x 20
440 (don't forget unit) and to square because we are finding the area
