Seven inches.
The circumference of a circle that has a diameter of 6.75 feet is about 21.2 feet.
You have to calculate the radius - half the diameter. Then square the radius, and multiply by pi (approximately 3.1416). If you want to do a mental estimate, round pi to 3.
The formula for a circumference is 2 times Pi times Radius. A diameter is twice the Radius, so the circumference is Diameter times Pi. 5 times Pi (3.14159) is approximately 15.70795. Pi has an endless number of digits to the right of the decimal point, so the best we can do is approximate.
Estimate: 3*10 = 30 inches Actual: pi*9.8 = 30.788 inches rounded to three decimal places

Seven inches.
The best estimate for the circumference of a circle that has a diameter of 6 is 18.9
The circumference of a circle with a radius r is P=2*pi*r so: r=P/(2*pi)=25.12/(2*pi)=3.9979721704684108345143601359176~4 cm
It is very close to 7 cm. Circumference = pi (2r) c = 6.2832 r = 44 44/6.2832 = 7.003
The 'best' estimate of the area of a circle with a radius of 7.62 meters is: 182.414692 m2
Use Circumference = 2 x radius x Pi Pi is 3.14159 appx. Therefore the circumference of your circle is 2 X 15 X 3.14159 inches or 94.25 inches or 7 feet 10 and 1 quarter inches
