Answer:
450 ml.
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder is given by:
In which r is the radius and h is the height.
A cylindrical drinking glass has a base radius of 3.2 centimeters and a height of 14.0 centimeters.
This means that
How many milliliters of water does the glass hold when it is full?
Radius and height are measured in centimers, so the volume will be in cubic centimeters, which is the same as milliliter. So
Rounding to the nearest millimeter, the answer is 450 ml.
Answer:
Step-by-step explanation:
No. If you reverse the prime number 23, you get 32 and that number is not a prime number.

Step-by-step explanation:
<u>Vertical Throw</u>
It refers to a situation where an object is thrown verticaly upwards with some inicial speed v_o and let in free air (no friction) until it completes its movement up and finally returns to the very same point of lauch. The only acting force is gravity
The projectile formula is given as
where t is time in seconds, h is the height in feet and v is the speed in ft/sec
We are required to find the time t where h=120 ft, knowing
Rearranging
This is a second-degree equation which will be solved with the formula
Two solutions are obtained
Both solutions are possible because the ball actually is at 120 ft in its way up and then when going down
Answer:
Step-by-step explanation:
Distance has to do with how far an object or a body has travelled. If a hiker starts at point P and walks 2.0 kilometers due east and then 1.4 kilometers due north, the total distance covered by the hiker will be:
Distance = 2.0km + 1.4km
Total distance travelled = 3.4km
The displacement is the distance covered in a specified direction. This is expressed using the Pythagoras theorem as shown:
R² = 2.0²+1.4²
R² = 4+1.96
R² = 5.96
R = √5.96
R = 2.44km
Hence the magnitude of the hiker’s displacement vector R is 2.44km
