the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46
Divide the circumference by pi, which is approximately equal to 3.14.
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
The radius of a circle with a circumference of 30 inches is: 4.77 inches.
what i do is square it 30x30 = 900 devide it by 100 and x it by 78.5398 =706.858278.5398% is correct for doing it this way.(78.5398163397425)Improved answer:Area of a circle = pi*radius2Area = pi*152 = 706.8583471 square inches
