Answer:
728 m^2
Step-by-step explanation:
There are 5 faces of the square pyramid.
You have to calculate area of each face and add them to find surface area.
Bottom face is a square, so
area = 14^2 = 196 m^2
All the other faces are triangle with same area, so
4 × triangle area
4 × ((1/2)×14×19)
4 × 133
532 m^2
Now add those areas,
(196 + 532) m^2
728 m^2
Answer:
480 calories
Step-by-step explanation:
4 ÷ 3/4= 5 1/3 servings
90 x 5 1/3= 480
Y2-y1/x2-x1.
-5-4 / 4-(-2)
-9 /6
-3 /2
Answer:
EF = 6m.
Step-by-step explanation:
Given that:
1) All the edges of the pyramid in the model have length 12m.
So, AB = 12m
2) E is the middle of AT, F is the middle of BT
So, EF is a line segment connecting the midpoints of ΔATB
So, by applying The Triangle Mid-segment Theorem
EF // AB and EF = 0.5 AB
So, EF = 0.5 AB = 0.5 * 12 = 6m
====================================
The Triangle Mid-segment Theorem:
The line segment connecting the midpoints of any two sides of a triangle has the following properties:
1) The line segment will be parallel to the third side.
2) The length of the line segment will be a half of the length of the third side.
