Answer:
The answer to your question is SA = 150.72 in²
Step-by-step explanation:
Data
Surface area = ?
height = 5 in
radius = 3 in
pi = 3.14
Formula
SA = 2πr² + 2πrh
Process
1.- Calculate the area of the bases
-Substitution
Area = 2(3.14)(3)²
-Simplification
Area = 2(3.14)(9)
-Result
Area = 56.52 in²
2.- Calculate the lateral area
-Substitution
Area 2 = 2(3.14)(3)(5)
-Result
Area 2 = 94.2 in²
3.- Calculate the total area
SA = 56.52 + 94.2
SA = 150.72 in²
Answer:
12%
Step-by-step explanation:
So in the first year they sold 650 bicycles.
Second year 572.
To find percentage you'll gain the difference 650 - 572 = 78 bicycles. Divide the deficit with initial sales (650).
72/650 * 100 (as we r finding percentage).
Its should give you 12%.
