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? Enter your answer in the box.  Part B What is the circumference, in feet, of the rug rounded to the nearest whole number? Enter your answer in the box.

A. 7 square feet

B. 9 feet

Step-by-step 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

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
