Seven inches.
The circumference of a circle that has a diameter of 6.75 feet is about 21.2 feet.
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.
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.
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
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
The 'best' estimate of the area of a circle with a radius of 7.62 meters is: 182.414692 m2
