Answer:
16) 9ft, C
17) 1440 cm^3, D
18) 314 m^2, B
Step-by-step explanation:
16) 18 / 6 = 27 / x
18x = 162
x = 9 (C)
17) 24 / 1,920 = 18 / x
24x = 34,560
x = 1440 (D)
18) Surface Area of a sphere = 4 * pi * radius^2 (4r^2)
SA = 4pi(5)^2
SA = 4pi25
SA = 100pi
SA = 100(~3.14)
SA = 314 (B)
Answer:
9*12=108
So he should need 108 bags.
