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
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
pi x (d/2)2 = 81pi/4
radius = circumference divided by 2 x pi so 10.99/6.28 = 1.75 metres
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
Law 5 of the official MCC Rules of Cricket states: The ball, when new, shall weigh not less than five and a half ounces (155.9 grams) nor more than five and three quarter ounces (163 grams), and shall measure not less than eight and thirteen sixteenths inches (22.4 cm), nor more than nine inches (22.9 cm) in circumference. The diameter can be found by dividing the circumference by pi, 3.141593.
Because the perimeter (circumference) is 2*pi*r is proportional to r. The area a = pi * r2 is proportional to r2
