Answer:158.76 cm^2
Step-by-step explanation:
Answer:
2x
Step-by-step explanation:
x ≥ 0
| x | = x .... absolute value will think all numbers are positive (or 0)
x + | x | = 2x
Answer:
a) Triangle
b) Rectangle
Step-by-step explanation:
A triangular prism that has an equilateral base and a height with the same length as the base of the prism.
a) Shape from horizontal slicing
A plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. So the cross section of the horizontal slicing is an equilateral triangle (all the sides of the triangle are equal).
b) Shape from vertical slicing
If the triangular prism is sliced vertically, the resulting shape would be a rectangle with a length that is the same as the base of the prism.
In order for a triangle to be congruent both triangles must have all 3 sides exactly the same number, it may be flipped, translated, or upside down, but as long as the 3 sides equal the same on both triangles it is considered a congruent triangle.
Volume of cylinder:
, where
is the radius and
is the height. This volume is
(cubic cm).
Volume of cone:
, with the same variables denoting the same parameters. This volume is
(also cubic cm).
The number of times it would take to fill the cylinder with water using the cone as a source would be
