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
If the length is taken as l , height is taken as h and breadth is taken as b . then
Area of the rectangular prism= 2( (l*b) + (b*h) + (h*l) )

Answer: 7 Switches will be made.
Step-by-step explanation:
number of switches
number of switches
- however you cannot have a fraction of a switch so you must round it to a whole number, which in this case is 7.
Yes it is. Ax+By=C is standard form. :)
