Answer: 137π
The usual formula for a circle centered at (a,b), with radius r,
(x - a)² + (y - b)² = r²
The area of the circle is πr², so 137π
The area of a circle with radius r is πr². So you need to find r such that
πr² = 56π
⇒ r² = 56
⇒ r = √56 = 2√14
Answer:
$80.73
Step-by-step explanation:
115 * 0.35 = $40.25 off
115 - 40.25 = $74.75 after sale
add tax (0.08)
74.75 * 0.08 = $5.98 tax
74.75 + 5.98 = $80.73 in total
C) 18 is your answer
