Diameter of cylinder A is 7cm, and height is 14cm. Diameter of cylinder B is 14 cm and height is 7cm. Find the area and volume.
Answers
Answer:
Diameter of cylinder A= 7 cm
Radius of cylinder A= 7/2 cm
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
Total Surface Area of Cylinder
= 2πr(r+H)
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

Answer:
_Cylinder A_
Diameter = 7 cm
Radius = d/2 = 7/2 cm
Height = 14 cm
TSA = 2πr(r+h)
=> 2 × 22/7 × 7/2 (7/2 + 14)
=> 11 × 35
=> 385 sq cm
Volume = πr²h
=> 22/7 × (7/2)^2 × 14
=> 11 × 49
=> 539 cu cm
_Cylinder B_
Diameter = 14 cm
Radius = d/2 = 7 cm
Height = 7 cm
TSA = 2 × 22/7 × 7 ( 7 + 7 )
=> 2 × 22 × 14
=> 616 sq cm
Volume = 22/7 × 7^2 × 7
=> 22 × 49
=> 1078 cu cm
Hope it Helps!!
