Answer:
3.576 cm
Step-by-step explanation:
radius of ball, r=?
Given:
Density, p = 0.600g/mL
mass, m= 115g
finding volume, v of ball by using formula p=m/v
v= m/p
= 115/0.600
=191.666 mL^3
=191.666 cm^3
Now using formula v= (4/3)πr^3 to find radius, r of the ball
r^3= 3v/4π
= 3(191.666)/4π
=45.75 cm
r =3.5767 cm !
Answer:
1. 24,000,000, i believe you divide, 300,000/80.
2. 4.065 seconds, i also believe you divide 5000m/1230.
Step-by-step explanation:
this right ans according to your question
Just divide 300 by 4 since 25% is 1/4
300/4 = 75
D. 75
Hope this helps!
