Answer:
The answer is 774.86
Step-by-step explanation:
Multiply (1.41*106) = 149.46
Multiply (5.9*106)=625.4
Add 149.46+625.4= 774.86

2(-2x-6)
= 2(-3)(x+3)
=-6(x+3)

Answer:
0.76m²
Step-by-step explanation:
In the above question, we are given the following information.
Radius = 0.4m
Height = 0.45m
To solve this question, The umbrella is CONICAL in shape and it has no BASE, we would be finding the lateral surface area of a cone. Since we are given height and radius :
Lateral Surface Area of a cone =
πr√(h² + r²)
= π × 0.4√(0.45² + 0.4)
= 0.7566m²
≈ Approximately = 0.76m²
Therefore, the amount of fabric needed to manufacture this umbrella is 0.76m²
