Answer:
Volume of the hemisphere = 
Step-by-step explanation:
It's a picture of a globe and a globe of the Earth is in the shape of a sphere.
We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".
Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.
If the radius of the Earth is 'r',
Volume of the hemisphere = 
Not sure why it needs to be a fraction, if I am missing something please tell me. 64 or 64/1
Answer:
y(0) = 0.25 feet


Step-by-step explanation:
We are given the following information in the question:
The displacement from equilibrium of an oscillating weight suspended by a spring =

where y is the displacement in feet and t is the time in seconds.
Here, cos is in radians.
1) t = 0

y(0) = 0.25 feet
2) t = 


3) t = 


The negative sign indicates the opposite direction of displacement.
