Question

PLEASE ASSIST me in this geometry problem!!

Answer 1

Given:

• A figure of cylindrical shape
• Radius = 2cm
• Height = 6 cm

To figure out :

• Total surface area
• Volume

Solution :

Note : Put the value of pi as 3.14

Volume = πr²h

• 3.14 × 2² × 6
• 3.14 × 4 × 6
• 3.14 × 24
• 75.36 cm³

Surface area = 2πrh + 2πr²

• 2πr ( r + h )
• 2 × 3.14 × 2 ( 2 + 6 )
• 12.56 × 8
• 100.48 cm²

Answer 2

Solution given:

B=12.56cm²

P=12.56cm

H=6cm

Surface area of cylinder=P*H+2B=100.48cm²

Volume=B*H=12.56*6=75.36cm³
