the circumference of a cylinder is 25.12 cm and the height is 8 cm what is the volume
Answers
Answer:
Volume of the cylinder = 401.55 cm³
Step-by-step explanation:
Given,
Circumference of a Cylinder = 25.12cm
Height of the cylinder(h) = 8cm
To Find :-
Volume of the Cylinder
Formula Required :-
Volume of the Cylinder = πr²h
Solution :-
Circumference of a Cylinder = 25.12cm
2πr = 25.12
radius(r) = 3.996cm
Volume :-
Volume of the Cylinder = πr²h
= 401.55 cm³
Volume of the cylinder = 401.55 cm³
Answer:-
- Valume of the cylinder is 401•55 cm³.
Step-by-step explanation:
Given that :-
- circumference of cylinder is 25.12 cm.
- height of cylinder is 8 cm.
To find :-
- what is the volume.
Formula used :-
- Valume of the cylinder = πr²h.
Where,
- π = 22/7
- r = radius
- h = height
Let us assume :-
- the radius of cylinder is r.
- the volume of the cylinder is V.
Finding the radius of cylinder :-
We know that,
- circumference of cylinder = 25.12 cm.
➪ 2πr = 25•12 cm.
➪ 2×22/7×r = 25•12 cm.
➪ 44/7×r 25•12 cm.
➪ r = 25•12×7/44 cm.
➪ r = 175•84/44 cm.
➪ r = 3•996 cm.
Finding the volume of the cylinder :-
We know that,
- Valume of the cylinder = πr²h.
➪ V = 22/7×(3•996)²×8 cm
➪ V = 22/7×15•97×8 cm
➪ V = 22/7×127•76 cm
➪ V = 2810•72/7
➪ V = 401•53 cm³.
Hence,
- the volume of cylinder is 401•53 cm³.
