False because the obtuse angle is to large to complement the right angle to diffrent angles can not be both of their compliments
1/10 of an hour (D) is correct. Hope this helped :)
Cone Volume = PI * radius^2 * height / 3, which can br rewritten as
Cone Volume = base area * height / 3
Cone Volume = 420mm * 60
Cone Volume = 25,200 cubic mm
First, we need to get the total area of the rectangular pool.
Area = l * w
Area = 20 ft * 50 ft
Area = 1000 ft^2
Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.
Area = l * w
456 = l * 20
l = 456 / 20
l = 22.8 ft.
So the walkway is 22.8ft wide.
To reproduce. But if this is suicidal type there are people here for you
