In a cylinder, each circle is 11cm in diameter and there is 20cm gap between them. What is the volume of the shape and the surface area?

Answer:

diameter (d) = 11 cm

radius (r) = d/2 = 11/2 = 5.5 cm

height (h) = 20

volume of cylinder (v) = pie × square of radius × height

= 22/7 × (5.5 ×5.5) × 20

=13310/7

= 1901.42 cm cube

surface area (LSA) = πdh

= 22/7×11×20

=4840/7

= 691.42 cm square

total surface area (TSA) = 2 ×AREA OF BACE + LSA

= 2π × square of radius + 691.42

= 2×22/7×(5.5×5.5) + 691.42

= 190.14+691.42

= 881.562 cm sq
