The circumference of a circle with a diameter of 18 inches is 56.5 inches.
18 inches
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
The diameter of a circle with a circumference of 18 is: 5.73
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
to find circumference of a circle the equation to use is: 3.14 multiplied by diameterso 3.14 * 18 =56.52THE FORMULA FOR CIRCUM OF A CIRCLE =II(pie)r2the diameter is=18...THE RADIUS =18/2 =9 CM=II 92=81 II CM2IN WORDINGS EIGHTY ONE PIE SQUARE CMAnother AnswerThe formula given above is for the area of a circle. The circumference of a circle whose diameter is known is obtained from the definition of pi, namely, the ratio of the circle's circumferene, C, to its diameter, D.pi=C/D so C=(pi)D =(3.14)(18cm)=56.55cm Roundedisn't there a more simple formula?????????????????????????????????
The two that have a circumference of 18 pie are a radius of 9 units and a diameter of 18 units.
The circumference of a circle with a diameter of 18 yards is: 56.55 yards (diameter x Pi = circumference).
A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
The area of a 18-inch diameter circle is: 254.5 square inches.
The diameter is about 18.
An 18" diameter circle has a circumference of about 56.5 inches.
