Ignoring the point and assuming a cylindrical pencil then the surface area would be made up of one rectangle and two circles.
The circles would have areas of 3.14 x 0.32 = 0.28cm2 giving a total for both ends of 0.56cm2
The rectangle would have a length of 15cm and a height of 3.14 x 0.6 = 1.88 thus having a total area of 28.26cm2
Thus the total area would be 28.26 + 0.56 = 28.82cm2
If you sharpen the pencil then the calculation becomes more complicated and you'd have the know the angle of the sharpened end

If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
The cylinder's circumference is approximately 50.27cm
The best estimate is 15 centimeters which is about 6 inches
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
Not enough information given.
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
The circumference of a circle with diameter of 15cm is about 47.12cm
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
Diameter = Radius*2 = 30 cm.

15*15 = 225 square centimetres.
176.715 cm2 (rounded)
The volume is 1,767 cm3
C = ~47.12 cm
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
