Answer:
A. 7 square feet
B. 9 feet
Explanation:
A circular rug has a diameter of 3 feet.
Part A
What is the area, in square feet, of the rug rounded to the nearest whole number?
Area of a circle = πr²
Radius = Diameter/2 = 3/2
= 1.5
Area of the circular rug = π × 1.5²
= 7.0685834706 square feet
Approximately to the nearest whole number
= 7 square feet
Part B
What is the circumference, in feet, of the rug rounded to the nearest whole number.
The circumference of a circle = 2πr
r = 1.5 feet
Circumference of the circular rug = 2 × π × 1.5 feet
= 9.4247779608 feet
Approximately to the nearest whole number = 9 feet
