2) 5a-16 or a=16/5
ANSWER
• Circumference: 18.84 ft
,
• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,

In this case, the radius is r = 3 ft and we have to use 3.14 for π,

Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,

In this case, r = 3 ft and π = 3.14,

Hence, the area of this circle is 28.26 square feet.
