Answer:
The volume of basketball is 7216.5 cm³.
Explanation:
Given data:
Radius of ball = 12 cm
Volume of ball = ?
Solution:
We will apply the volume formula of sphere.
V = 4/3 ×π×r³
we know that,
π = 22/7
r = 12 cm
Now we will put the values in formula.
V = 4/3 × 3.14 × (12 cm)³
V = 4/3 × 3.14 ×1728 cm³
V = 7216.5 cm³
Thus, the volume of basketball is 7216.5 cm³.
Answer:
0 kgm/s
Explanation:
The momentum of Bob while resting at the river is 0 kgm/s.
This is because the momentum of any object at rest is 0.
Momentum is the quantity of motion a body contains. It is mathematically expressed as;
Momentum = m x v
m is the mass
v is the velocity
So at rest, the velocity of a body is 0m/s and therefore, the momentum is O
Asteroids are made up of metals and rocky material , while comets are made up of ice ,dust and rocky material.
Answer:
A_________________________
Answer:
v = 600 mph
Explanation:
Given data:
Distance cover by the plane = 3000 miles
Time taken by it = 5 hours
Velocity = ?
Solution:
Formula:
v = d/t
v = velocity
d = distance
t = time
Now we will put the values in formula.
v = 3000 miles/ 5 h
v = 600 mph
mph = miles per hour
