Answer:
<h3><em>THE LAST ONE IS THE CORRECT ANSWER BECAUSE ...................</em></h3>
Step-by-step explanation:
A PYRAMID IS A FOUR DIMENSHION FIGURE IT MEANS IT HAS FOUR TRIANGLES : <u>SO CORRECT ONE IS IT CONTAIN ANY NUMBER OF TRIANGLES OR GREATER THAN OR EQUAL TO FOUR.</u>
Answer:
Angle CAB
Step-by-step explanation:
Given that a triangle ABC is rotated 100 degrees counterclockwise about a point P. New triangle formed is Triangle A'B'C'.
A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise. The fixed point in which the rotation takes place is called the center of rotation.
Here fixed point is P and angle is 100 degrees
The property of rotation is rotation is a transformation of transforming a geometric figure to a similar figure.
In other words, by rotation here ABC will be similar to A'B'C'
Hence angles of ABC will remain equal to angles of A'B'C' in that order.
So m/_ C'A'B'=m /_CAB
The area of any regular polygon is equal to one half the product of the apothem and the perimeter of the polygon. A regular polygon is any polygon that has equal length of its sides. A pentagon has 5 sides so if it is a regular pentagon then the perimeter is 5 times the length of one side. The apothem of a polygon is the length of a line from the center of the polygon to the middle of one of its side. We calculate the area as follows:
Area = apothem (perimeter) / 2
Area = 7 ft (5 (10 ft)) / 2
Area = 175 ft^2
Answer:
187.96
Step-by-step explanation:
yeah
answer
given
v=2100cm³
h=3r
v=1/3πr²h
soln
v=1/3πr²h
2100cm³=1/3×π×r²×3r( you will insert 3r in the place of h.)
2100cm³=3π/3×r³(cancel 3 by 3)
2100cm³= πr³
r³=2100cm³/3.14 ( π=3.14)
¾r³=¾2100cm³/3.14(I make them cube root.sorry I can't use the real cube root so I replace it by ¾)
r=8.74…
