You divide the percentage by 100. So that would be 0.875
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 =
Answer:
Step-by-step explanation:
<u>Find the z-score:</u>
- z = (x - μ) / σ
- z = (65 - 70) / 4 = -1.25
From the z-score table we get corresponding value of 0.1056
<u>Proportion of scores higher than Cam's score:</u>
- 1 - 0.1056 = 0.8944 = 89.44%
