Diameter of the cylinder is 7 cm and the height is 14 cm diameter of cylinder b is 14 cm and height is 7 cm without doing any calculation volume of both the cylinders check whether the cylinder with other value also has greater surface area
Answers
Answer:
Step-by-step explanation:
The Radius of cylinder A is half of the radius of cylinder B it means the radius of cylinder B is Greater . When finding the volume we have to square the radius & square of radius gives more value .
The volume of cylinder B is Greater then Volume of Cylinder A.
The Diameter of cylinder A= 7 cm
The Radius of cylinder A= 7/2 cm
The Height of cylinder A= 14 cm
Volume of cylinder = πr²H
Volume of Cylinder A= (22/7)(7/2)² 14
= (22/ 7) (49/4)× 14
= 539 cm³
Diameter of cylinder B= 14 cm
Radius of cylinder B= 14/2=7 cm
Height of cylinder B= 7 cm
Volume of Cylinder B= (22/7)(7)2 7
= 22×49
=1078 m³
Therefore, the Volume Of Cylinder B is greater than Volume of cylinder A
The Total Surface Area of Cylinder
= 2πr(r+H)
The Total Surface Area of Cylinder A= 2×(22/7)×(7/2)(7/2 +14)
= 22((7+28)/2)
= 22(35)/2
= 11×35
= 385 cm²
Total Surface Area of Cylinder B= 2×(22/7)×(7)(7+7)
= 44 × 14
= 616 cm²
Therefore, the surface area of Cylinder B is also greater .
