The other answer is wrong. It says 4 round trips so 4x2=8. So 8x47 is your answer
The expression for volume is l•w•h (length times width times height). For example, you could say:
Amber is filling a cube with sand. She wants to find out the volume of the box to find out how much sand she needs. She knows that the length is 7 inches, the width is 3 inches, and the height is 4 inches. What is the volume of the cube?

<h3>Given:-</h3>
- radius = 7 inches
- height = 9 inches

<h3>To find:</h3>

we know:-


So:-
⇢SA of cylinder=2πrh+2πr²

⇢SA of cylinder = 2πr(h+r)

⇢SA of cylinder = 2 × π × 7(7 + 9)

⇢SA of cylinder = 2 × π × 7 (16)

⇢SA of cylinder = 2 × π × 112

⇢SA of cylinder = 2 × 112 × π

⇢SA of cylinder = 224π inches ²
