There is two ways to attempt this problem. The first is that you could prove that angle CDE is congruent to angle DAB (of which I'm not totally sure is possible) or option two. Your second choice is to prove that Line segment DE is a flat line because line segment AB is also a flat line.
Answer:
5/3
Step-by-step explanation:
Area of a parallelogram = b*h (base*height)
b= 12cm
h= 18cm
Therefore:
= 12*18 cm
Area of the parallelogram = <u><em>216cm</em></u>
Answer:
9pi approximately 28
Step-by-step explanation:
we have the formula - pi r^2
which we know the diameter is 6 m and the surface is a semi circle
the radius is 3 so then we have pi 3^2
which becomes 9pi which is about 28.2
rounding to 28
hope this helps!!
