Answer:
The area which would be painted grey will be "47.7812 ft²".
Step-by-step explanation:
The given values are:
Radius of circle, r = 5.4 feet
Value of pi, π = 3.14
As we know,
Area of Semicircle = 
On putting the values in the above formula, we get
= 
= 
= 
=
4320 9608 rounded to the nearest one thousand is 30,000
Answer:

Step-by-step explanation:
Distance between two points:
Suppose that we have two points,
and
. The distance between them is given by:

Distance from A(-8,-3,-2) and B(-4,8,0)



It would become 4.3 because 6 is 5 or greater so you round up.
Parallel lines share the same slope. Thus, every line in the form y=(1/2)x+n will be parallel, where n is some constant.
