Answer:
Volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π
Step-by-step explanation:
Given: Diameter is 9 cm
Height is 15 cm.
First lets find out the radius of cylinder.
As given, diameter is 9 cm
we know, radius= 
Radius= 
Now, finding the volume of the cylinder.
Formula; Volume of cylinder= 
where r is radius and h is height of cylinder.
⇒ Volume of cylinder= 
⇒Volume of cylinder= 
⇒Volume of cylinder= 
Taking π = 3.14
⇒ Volume of cylinder= 
⇒ Volume of cylinder= 953.77 cm³
Hence, volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π.
