Question

if the lateral surface area of right circular cylinder of radius 5 cm is 220cm² the find height​

Answer 1

Answer:

h= 7cm

Step-by-step explanation:

2phirh = 220

phih = 22

h = 7cm

Answer 2

Answer :

• Height is 7cm

Given :

• Radius is 5cm
• Lateral surface area of right circular is 220cm²

To find :

• Height

Solution :

As we know that,

• Lateral surface area of cylinder = 2πrh

Where,

• r is radius
• h is height

》Lateral surface area of cylinder = 2πrh

》 220 = 2 × 22/7 × 5 × h

》220 = 44/7 × 5 × h

》220 = 31.4 × h

》h = 220/31.4

》h = 7cm

Hence , Height is 7cm

More Explanation :

• Total surface area of cylinder = 2πr(r + h)
• Volume of cylinder = πr²h
• Lateral surface area of cylinder = 2πrh
• Cylinder is 3D shape
