Step-by-step explanation:
Answer:
C=2πr=2·π·41≈257.6106
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Earth volume: (3/4).π.(6371)³ = 1,0832x10¹² km³
Pluto volume: (3/4).π.(1171)³ = 6,555,189,765 km³
How many spheres the size of Pluto does it take to have the same volume as earth?
volume Earth/ volume Pluto = 1,0832x10¹² / 6,555,189,765 = 165.25
We are given the distance as a function of time:
s = 4.9 t^2 + 350
To get the velocity, we take the first derivative and
substitute the value of t = 2:
ds = 9.8 t dt
ds / dt = 9.8 t
velocity = 9.8 (2)
<span>velocity = 19.6 m/s</span>
