Question

if a metallic sphere of radius 4.2 cm is melted and recast into the shape of a cylinder of radius 6 cm ,then the height of the cylinder is

Answer 1

this is the answer for given question

Answer 2

Answer:

• Height of the cylinder = 2.74 cm

Step by step explanation:

Extra Information:-

1). For cylinder:

• CSA = 2πrh
• TSA = 2πrh + 2πr²
• Volume = πr²h

2). For cube:

• CSA = 4a²
• TSA = 6a²
• Volume = a³

3). For cuboid:-

• CSA = 2(bh + hl)
• TSA = 2[lb + bh + hl]
• Volume = lbh

4). For Cone:-

• CSA = πrl
• TSA = πrl + πr²
• Volume = 1/3 πr²h

5). For Sphere:-

• CSA = TSA = 4πr²
• Volume = 4/3πr³

6). For hemisphere:-

• TSA = 3πr²
• CSA = 2πr²
• Volume = 2/3 πr³
