15 cm is a measure of length and a length has no surface.
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
answer me
Slant height is 39.98 cm
15cm = 5.9 inches.
Complete surface area = (2*pi*72)+(14*pi*15) = 308*pi square cm
15*15 = 225 square centimetres.
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2

Not enough information given.
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
Slant height is 39.98 cm
15cm-58mm equals = -43
15cm = 5.9 inches.
Complete surface area = (2*pi*72)+(14*pi*15) = 308*pi square cm
The surface area of a box 15cm x 12cm x 8 cm is 2 times 15cm times 12cm, plus 2 times 15cm times 8 cm, plus 2 time 12cm times 8 cm, or 792cm2. However, this is only the surface area - the actual wrapping paper required would depend on the method of wrapping and how much overlap is desired. Since you would not want to splice the paper, you certainly would need more that 792cm2 but, again, that depends on your wrapping style.
The circumference of a circle with diameter of 15cm is about 47.12cm
The circumference of a circle, if the diameter is 15cm, is about 47.12cm
