Answer:
8 days
Step-by-step explanation:
90/3 = 30 mi/day
240/30 = 8 days
it will take him 8 days (7.98 in you don't round)
90 -240= 150
150/90 = 1.6666....
1.66 * 3 = 4.98
4.98+3 =7.98 (8 if you round)
56/3 pi cm^3
1/2 volume of sphere = 1/2 4/3 pi r^3
volume of cone 1/3 pi r^2 h
r =2 h = 10
result : 56/3 pi cm^3
The area of the triangle.
z<1.5
