Answer:
41.8887 cm^2
Step-by-step explanation:
area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94
120 / 360 = 1/3
153.94 / 3 = 51.3134
now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247
subtract
51.3134 - 9.4247 = 41.8887
Answer: The price of meal before the tip = $34.
Step-by-step explanation:
Given : The percentage of tip = 22% = 0.22 ( we divide a percentage by 100 to convert it into decimal)
Total amount paid ( including tip) = $41.48
Formula for Total bill = Price of meal + Tip amount , where Tip amount= 22% of Price of meal.
Let x be the price of meal, then
Total bill =x + 0.22 x (x )
⇒ $41.48= x(1+0.22) [ By distributive property]
⇒ $41.48 = x (1.22)
⇒ x= ($41.48) ÷ 1.22
⇒ x= 34
Hence, the price of your meal before you applied the tip = $34.
