Answer:
87.92 mm²
Step-by-step explanation:
Given:
- Radius of circular base: 2 millimeters
- Height of cylinder: 5 millimeters
<u>It should be noted:</u>
- Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)
When the measures are substituted, we get the following expression:
Multiply the constants and substitute π as 3.14.
- ⇒ 20π + 2π(4)
- ⇒ 20π + 8π
- ⇒ 20(3.14) + 8(3.14)
Finally, simplify the expression to determine the surface area.
- ⇒ 20(3.14) + 8(3.14)
- ⇒ 62.8 + 25.12
- ⇒ 87.92 mm²
Answer:
Step-by-step explanation:
0.333333 = 1/3
can check through dividing 1 by 3
0.125 = 125/1000 = 25/200 = 5/40 = 1/8
0.166666 = 1/6
0.1 = 1/10
0.66666 = 2/3
0.2 = 2/10 = 1/5
0.75 = 75/100 = 15/20 = 3/4
