P(7,6), Q(1,6), R(4,2)
We have PQ parallel to the x axis. We'll call that the base,
b = 7 - 1 = 6
The altitude is then the y difference h = 6 - 2 = 4
The area is
Answer: 12 square units
In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:
(7,6), (1,6), (4,2)
(1,6), (4,2), (7,6)
The area is then half the absolute value of the sum of the cross products:
Answer:
Option A . 1708 bags
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the volume of the silo
The volume of the silo is equal to the volume of a cylinder plus the volume of a cone
so
we have
---> the radius is half the diameter
substitute
Remember that
The silo is approximately 85% full
so
The volume of grain in the silo is
step 2
Find the number of bags of grain
Divide the volume of grain in the silo by the volume of one sack
