The definition of math is the overall group of sciences that study numbers, shapes and their relationships. An example of math is arithmetic, the study of addition, subtraction, multiplication and division. ... (uncountable, North America) Arithmetic calculations; (see do the math).
The correct answer is:
there must be at least two lines on any plane because a plane is defined by 3 non-collinear points.
Explanation:
Since a plane is defined by 3 non-collinear points, we could have: a line and a point not on that line; two intersecting lines; two parallel lines; or simply 3 non-collinear points.
For 3 non-collinear points: If none of the 3 points are collinear, then we could have 3 lines, 1 going through each point. These lines may or may not intersect. If two of the 3 points are collinear, then we have a line through those 2 points as well as a line through the 3rd point.. Again, these lines may intersect, or they may be parallel.
Answer:
143.7cm^2
Step-by-step explanation:
Given data
Volume= 576cm^3
Radius= 8cm
The expression for the volume of cylinder is
V= πr^2h
substitute
576= 3.142*8^2*h
576= 3.142*64*h
576= 201.088h
h= 576/201.088
h=2.86cm
The formula for finding the lateral area of a right circular cylinder is:
A=2πrh
substitute
A= 2*3.142*8*2.86
A= 143.7cm^2
Hence the area is 143.7cm^2
Answer:
584
Step-by-step explanation:
17510 divided by 30 is 583.66 but you can have part of a person so you round up.
