Answer:
Step-by-step explanation:
we can break up the figure into 2 rectangles by extending the 8m side downward until it meets the bottom (see image)
Area of this rectangle = 10 * 2 =20 sq meters
Area of the other rectangle = 8 *2 = 16 sq meters
Total area = 36 sq meters
Volume of a Cylinder = pi * r^2 * h
V / (pi*r^2) = h
12157 / (pi * 9^2) = h = 47.774
1)a parallelogram is a quadrilateral with opposite sides being parallel so the lines AB must equal CD or otherwise it wouldn't be a parallelogram
2)for a quadrilateral to be proven to be a parallelogram the consecutive angles has to be supplementary which means they add up to 180 or for example you could slice the parallelogram in half down the middle you could piece the two consecutive angles together to make 180 degrees
