Make nine equiel distances marks on the perimeter or circumference. Draw a line from the centre to each of these marks.

9x6=54 square feet

About nine feet.

15 feet 7 inches.

Since there are 3 feet in 1 yard, therefore there are 27 feet in 3 yards.

The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles

Easy. The circumference of a circle is found by multiplying the diameter by Pi (3.1416). So, in this case: 9 x Pi (3.1416) =a circumference of 28.2744

If you triple the radius of a circle . . . -- You should not expect anything to happen. Those around are likely to remain completely unaware that you have done anything to your circle. -- You wind up with a circle that's three times as big as it used to be. -- The diameter of the circle is three times the original diameter. -- The circumference of the circle is three times the original circumference. -- The area of the circle is nine times the original area.

radius = circumference divided by 2 x pi so 10.99/6.28 = 175 centimetres

Measure using a protractor and then split it every 40degrees. DoNe

pi x (d/2)2 = 81pi/4

radius = circumference divided by 2 x pi so 10.99/6.28 = 1.75 metres

The radius will be 10.5in or 0.875ft. pi r 2 is 346.36 square feet, not either of the 2 you've listed

Make nine equiel distances marks on the perimeter or circumference. Draw a line from the centre to each of these marks.

Radius = 26.69/2*pi = 4.248 meters rounded to 3 decimal places
