Answer:
48 π
Step-by-step explanation:
Area of Circle =πr∧2
Big Circle Area = π(8)∧2 = 64π
Small Circle Area =π(4)∧2= 16π
Shaded Region = 64π - 16π = 48π
130 divided by 2.5. that is how you get your answer.
Answer: Tablets because they increase in sales by 467%
Step-by-step explanation:
The item with the greatest increase is the one that has the highest percentage increase in the 3 years.
Each box represents 20 units sold.
Desktop Computers:
= (2017 sales - 2015 sales) / 2015 sales * 100%
= (160 - 100) / 100 * 100%
= 60%
Laptops:
= (280 - 160) / 160 * 100%
= 75%
Tablets:
= (340 - 60) / 60 * 100%
= 467%
