A ball is thrown vertically upward by a cricket player with an initial velocity of 40 m/s. if motion of ball accelerated by 10 m/s^2, then calculate 1) the maximum height reached by the ball
2) the distance covered by the ball when it reaches the player's hand
3) the displacement covered by the ball when it reached player's hand

The volume of a right circular cylinder can be approximated as follows: volume = ? r2h; where r is the radius of the cylinder and h is the height of the cylinder; ? is a constant that is roughly equal to 3. using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 7 meters
