the equation to find circumference is C=2*pi*radius
so when you have a radius of 18 inches, C=113.097

36 inches. The radius is the distance from the centre to the outside or circumference and trhe diameter is the distance across passing through the centre. Therfore the diameter is twice the distance of the radius.
18 inches
Well, isn't that just a happy little question! If the diameter of the wheel is one yard, which is 36 inches, then the radius would be half of that. So, the radius of the wheel would be 18 inches. Just remember, there are no mistakes, just happy little accidents!
Assuming 9m refers to the radius, the diameter is 18 m and the circumference is 56.5 m
To calculate the area in square feet, you first need to convert the dimensions to feet. Since 1 foot is equal to 12 inches, 18 inches is equal to 1.5 feet. Therefore, 18 inches by 18 inches equals 1.5 feet by 1.5 feet, which is 2.25 square feet.
