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

What is the surface area of a pencil with a 15cm length and a 0.6cm diameter and a 2cm long point?
Not enough information given.
What is the radius of a 15cm circle?
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
What is the best estimate for the length of a pencil 15 centimeters or 15 meters?
The best estimate is 15 centimeters which is about 6 inches
Work out the perimeter of the semi-cirle when diameter is 15cm?
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).
Is 15cm greater than 150mm?
They are the same measurement. 15cm = 150mm (conversion is 1cm=10mm)
