Answer:
The Area of shaded portion is 314000 cm²
Step-by-step explanation:
Given as :
The circle is drawn with radius = r = 10 cm
Two portion of circle is shaded
∵ two portion is shaded means whole the circle is shaded now
Let The area of shaded portion = A = area of circle
∵ Area of circle = A = π × radius²
where π = 3.14
Or, A = 3.14 × r²
Or, A = 3.14 × (100)²
Or, A = 3.14 × 10000
Or, A = 
I.e A = 314000 cm²
So, The Area of shaded portion = A = 314000 cm²
Hence, The Area of shaded portion is 314000 cm² Answer
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.
Answer:
-7
Step-by-step explanation:
you divide both sides by -2 and 14/-2 is equal to -7
