Question

Find the height of cylinder whose radius is 7cm and total surface are 968cm sq

Answer 1

Step-by-step explanation:

Given :-

• Radius = 7 cm
• TSA of cylinder = 968 cm²

Find :-

• Height = ?

We know that

TSA of cylinder = 2πr ( h + r )

• 968 = 2 × $\frac{ 22 }{ 7 }$ × 7 ( h + 7 )
• 968 = 2 × 22 ( h + 7 )
• 968 = 44 ( h + 7 )
• $\frac{ 968 }{ 44 }$ = h + 7
• 22 = h + 7
• 22 - 7 = h
• 15 = h

Height of the cylinder = 15 cm

Answer 2

the solution is 15cm sq
