Answer:
The total surface area of the square pyramid is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of four triangular faces
so
Answer:
5016
Step-by-step explanation:
5500 - 324(area of pool)=5176
5176-160(area of walkway)=5016
Answer:
The correct options are;
1) The shape maps unto itself after a rotation of 270 degrees
2) The smallest angle of rotational symmetry is 90 degrees
3) The shape maps unto itself after a rotation of 180 degrees
Step-by-step explanation:
We note that the shape of a cross which consists of two equal members (segments) bisecting each other at right angles such that when a member is placed vertically upright, the other member will be horizontal, therefore we have;
After rotation by 90 degrees, the vertical member will become horizontal and vice versa
After rotation by 180 degrees, the vertical member will become horizontal and vice versa again
Similarly, after rotation by 270 degrees, the once vertical member will become horizontal and the horizontal member will become vertical
Just set each expression equal to 3(n+6). If you get the same answer on both sides (x=x) then that expression is equivalent! :)
A product is zero if and only if at least one of the two factors is zero. So, you need either
or
In the first case, the equation reduces to
In the second case, we have
So, you need one of the following three to happen:
I assume you have a table to look up for these known values. If you have trouble solving for , feel free to hit me up.
