Answer:
Perimeter of the final star = 40 cm²
Step-by-step Explanation:
The perimeter of the six-pointed star is the sum of the sides of the 6 equilateral triangles that form a boundary around the star.
1 triangular tiles gas a perimeter of 10cm.
Only 2 out of the 3 equal sides of each of the 6 equilateral triangles form the boundary of the final star.
Therefore, perimeter of the final star = ⅔ of the total perimeter of 6 triangular tiles
= ⅔ of (10*6)
= ⅔*60
= 2*20
Perimeter of the final star = 40 cm²
1. false because it has only 2 triangular faces
2. true
3. true
4. i think its false, it has four
5.
Answer:
by adding a transverse line to it interesting both of them
Answer:
h = 
<u>Step-by-step explanation:</u>
T= 2rπh + 2πr²
Subtract terms that don't include the indicated variable from both sides:
T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh
Divide values being multiplied by indicated variable from both sides:
T - 2πr² = 2rπh ⇒ = h
