Blonde and 7 hope this helps :))
Answer:
Step-by-step explanation:
Given: The diameter of the cylindrical base of the pencil is 10 mm and the height of the cylinder is 70 mm, while the height of the cone is 12 mm
To find: surface area of the pencil
Solution:
Radius of the cone = Radius of the cylinder (r) = diameter/2 =
Height of the cylinder (H) = 70 mm
Height of the cone (h) = 12 mm
Slant height of the cone (l) =
Curved surface area of cone =
Surface are of cylinder = curved surface area of cylinder + base area of cylinder
So,
surface area of the pencil = Curved surface area of cone + Surface are of cylinder =
5 - 5/7 is 30/7 which is 4 2/7
The range is the difference between the highest and lowest pays.
Highest pay: GS-5 - 2,252
Lowest pay: GS-1 - 1,461
Range = 2252 - 1461 = 791
The answer is D. $791
