You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.

Then,

So,

radius is approximately 3.4cm

Answer:
777.9 meters
Step-by-step explanation:
Notice that the angles of the right triangle are 40 and 50 degrees, with the 500 meter side adjacent to the 50 degree angle. Now, we can set up an equation: cos (50 degrees) = 500 / x. Use a calculator to find that the answer is 777.9.
Answer: v= 56 ft per second

Given: A quarterback throws a football to a teammate.
Projectile motion formula is given by :-
, where 
Now, to find v at h=5 and t=3.5, substitute these values in the above equations, we get

1.4171428571428571428571428571429 milimeters per year or,
0.14171428571428571428571428571429 centimeters per year.
Step-by-step explanation:
2x^2 + 8x - x -4
