Answer:
The correct answer will be "0.756596 m²".
Step-by-step explanation:
The given values are:
The radius of an umbrella,
r = 0.4 m
The height of an umbrella,
h = 0.45 m
As we know,
The lateral surface of an umbrella will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
So that the amount of fabric needed will be "0.756596 m²".
Answer:

6a(2ab-3b²-5b³)
6ab(2a-3b-5b²)
Answer:
540 degrees
Step-by-step explanation:
Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...
They are different because perpendicular lines cross one another in a specific way. The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing. It could be at any angle.
