The hint is wrong.
Volume of a cylinder is π r² h .
For the cylinder in the question,
Volume = ( π ) · (1.5 cm)² · (5.3 cm)
= ( π ) · (2.25 cm²) · (5.3 cm)
= ( π ) · (11.925 cm³)
= 37.4 cm³
False. They have a definite volume, but they take the shape of the container they are in.

Chemical energy is converted to heat and light energy.
To find the velocity of the bullet just before reaching the ground, we use the formula.
Vy = Vosen (30 °) + gt (1).
For that we need to know the time it takes for the bullet to reach the ground from the moment it is fired.
For that we use the formula:
Xy = Xo + Vosen (30 °) * t + 0.5gt ^ 2 (2)
where:
Vy = Component of the speed in the y direction (vertical)
Vo = initial velocity of the bullet at the exit of the cannon
g = acceleration of gravity
Xy = vertical component of the position.
Xo = initial position.
t = time.
To find the time it takes for the bullet to reach the ground, we make Xy = 0 and clear t.
then it would be:
0 = 10 + 80sen (30 °) * t +0.5 * (- 9.8) t ^ 2.
The solution to that equation is:
t = 8.4 seconds.
We substitute that time in equation (1) and clear Vy.
We have left:
Vy = 80 * sin (30 °) + 9.8 * (8.4)
Vy = 42.38 m / s
Answer: A circuit is electric wire that sends connection and signals to other bulbs or batteries that are connected to the circuit. There’s two different kinds of circuits, Series Circuit and Parallel Circuit.
Explanation: This is because Circuits is a term used in physic s
