Answer:

Area of shaded region = 329.70 cm²

Step-by-step explanation:

Area of a circle = πr²

Area of bigger circle = 3.14 × 11²

= 3.14 × 11 × 11

= 379.94 cm²

Area of smaller circle = 3.14 * 4²

= 3.14 × 4 × 4

= 50.24 cm²

Area of shaded region

= Area of bigger circle - Area of smaller circle

= (379.94 - 50.24) cm²

= 329.70 cm²

Alang owns a small business selling ice-cream. He knows that in the last week 62
anzhelika [568]

Step-by-step explanation:

last week there were

62 + 60 + 2 = 124 customers.

that means that the fraction of the customers, who paid by credit card, was

2/124 = 1/62

in situations like that, when we use history data and try to predict future behavior, we use that past experience and extrapolate to a predicted result.

we simply say that we expect the same fraction, 1/62, if customers to use credit cards.

for the absolute number of predicted credit card customers we multiply the predicted number of customers by the expected fraction

1000 × 1/62 = 500/31 = 16.12903226... ≈ 16

so, he expects 16 credit card customers.
