Answer:
50.24
Step-by-step explanation:
A= πr2
314/100×4×4=50.24





Consider a
ABC right angled at C and
Then,
‣ Base [B] = BC
‣ Perpendicular [P] = AC
‣ Hypotenuse [H] = AB

Let,
Base = 7k and Perpendicular = 8k, where k is any positive integer
In
ABC, H² = B² + P² by Pythagoras theorem

Step-by-step explanation:
Answer:
The main answer: $4.84
Step-by-step explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
