learn man but there u go
Mechanical energy = potential energy + kinetic energy
The ball is on the ground so it has no potential energy. that's all i know.
Answer:
42.417 cm³
Explanation:
The formula to find the volume of a cone is :
V =
× π r² h
Here,
r ⇒ radius ⇒ 3 cm
h ⇒ height ⇒ 4.5 cm
<u>Let us find it now.</u>
V =
× π r² h
V =
× π × 3 × 3 × 4.5
V =
× π × 9 × 4.5
V =
× π × 9 × 4.5
V =
× π × 40.5
V =
× 3.142 × 40.5
V =
× 127.251
V = <u>42.417 cm³</u>
