60 mins I think because 1 hour equals 60 mins
The answer is a hope this helps
Answer:
72 degrees.
2 parallel lines cut by a transversal result in alternate interior angles.
Volume of the sink
The formula for a complete sphere is V = (4/3) pi r^3
1/2 a sphere is just one half that amount V = 1/2 (4/3) pi r^3 = (2/3) pi r^3
r = 20/2 = 10 a radius (r) is 1/2 d
V = (2/3) 3.14 10^3
V = 2093 cubic inches.
First cone
V = (1/3) pi r^2 h
pi = 3.14 (always)
r = d/2 = 8/2 = 4 in
h = 6 in
Volume = (1/3) * 3.14 * 4^2 * 6
Volume = 1/3 * 301.44
Volume = 100.8
The number of scoops needed is
Scoops = volume of hemisphere / volume of cone
scoops = 2093/100.8
Scoops = 20.6
Scoops should be rounded to 21
2nd Cone.
You just need to substitute the numbers for the second scoop into what I have done above.
The answer is 83.3 which you have to round to 84. He better stick with the first cone (or is it a she).
