Formula for area of circle:
A=πr²
Here diameter, d= 6 cm
Radius, r= d/2 = 6/2 = 3 cm
Put values
A= 3.14 x 3²
A=3.14 x 9
A=28.26 cm²
Answer: 28.26 cm²
The percent of change = ((new value - old value) / old value) × 100%
Our new value = $261.50
Our old value = $382
Plug our values into the equation above.
(($261.50 - $382) / $382) × 100% = -31.54%
