Answer:
(1)C- Trapezoid
(2)D-20 square feet
Step-by-step explanation:
<u>Question 1</u>
A cross-section of a rectangular pyramid cut perpendicular to the base but not passing through the top will have two parallel sides where one of the sides will be longer. Therefore, the shape which describes the cross-section will be a trapezoid.
<u>Question 2</u>
The base of the Triangle = 5 feet
Height of the Triangle = 8 feet

360 degrees in a circle
32/360 of total area is sector area
area=pir^2
r=8.5
area=pi8.5^2
area=226.980022 mm^2
multiply it by 32/360
sector=20.17600195555556
round
sector=20.2
