Radius = r = 1 foot
Angular velocity = w = 1 revolutions in 4 seconds
So,
w = 0.25 revolutions per second
Since,
1 revolution = 2π radians
We can write the above equation as:
w = 0.25 x 2π radians per second = 0.5π radians per second
Linear Velocity = v = r w
Using the values, we can write:
v = 1 x 0.5π
= 0.5 π
= π/2 feet per second
Therefore, the correct answer is option B
Answer:
Volume= 729 m³
Step-by-step explanation:
The volume is the space occupied by a thing.
The volume of the right angled rectangular prism is given by
Volume= length * breadth* height
Since all the sides are equal we can calculate the volume by
V= L*w*h
V= 9m*9m*9m = 729 m³
A rectangular prism looks like this.
