Find The Total Surface Area Of This Cylinder 24cm 18cm class=

Sagot :

Answer:

  • 2262.8 cm²

Step-by-step explanation:

We know that:

  • Surface area of cylinder formula: 2πrh + 2πr²
  • Height = 18 cm
  • Diameter = 24 cm
  • Radius = 12 cm

Solution:

  • Surface area of cylinder = 2πrh + 2πr²
  • => (2 x π x r x h) + (2 x π x r²)
  • => (2 x 22/7 x 12 x 18) + (2 x 22/7 x 12²)
  • => (44/7 x 12 x 18) + (44/7 x 144)
  • => (44/7 x 216) + (44/7 x 144)
  • => (1357.7) + (905.1)
  • => 2262.8 cm² = Surface area of cylinder

Hence, the surface area of the cylinder is 2262.8 cm².
