Find the total surface area of this cylinder.
24cm
18cm

2262.8 cm²

Step-by-step explanation:

We know that:

Surface area of cylinder formula: 2πrh + 2πr²Height = 18 cmDiameter = 24 cmRadius = 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.
