Answer:
volume of a cylinder = 401.92cm³
Step-by-step explanation:
to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder
volume of a cylinder = πr²h
given that
height of the cylinder = 8cm
radius of the cylinder = 4cm
volume of a cylinder = π × (4cm)² × 8cm
volume of a cylinder = π × 16cm² × 8cm
volume of a cylinder = π128cm³
value of π = 3.14
volume of a cylinder = 3.14 × 128cm³
volume of a cylinder = 401.92cm³
S=d/t
45=29/t
t=45/29
convert to min
t=45/29 *60=38.66min
