Answer:
125.6 cm²
Step-by-step explanation:
Area of the shaded region = area of larger circle - area of the smaller circle
Area of the smaller circle = πr²
π = 3.14, r = 3 cm
Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²
Area of larger circle = πr²
π = 3.14, r = 7
Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²
Area of the shaded region = 153.86 - 28.26 = 125.6 cm²
Answer:
Number of customers (double taco)= 45
Step-by-step explanation:
Giving the following information:
Double taco order rate= 15% = 0.15
Total number of customers= 300
<u>To calculate the number of customers that order two tacos, we need to use the following formula:</u>
Number of customers (double taco)= Double taco order rate*total number of taco
Number of customers (double taco)= 0.15*300
Number of customers (double taco)= 45
