Area of a circle = pi*radius squared
You can calculate the area of a circle with the formula: A = pi x radius2 If the 30 inches refers to the diameter, divide it by 2 to get the radius.
The radius is 30 inches.
A circle with a radius of 30 meters has an area of 2827.43 square meters.
If a circle circumference is 30 the radius is: 4.77
Area of a circle = pi*radius squared
Your answer will be 15 and for area its 28.26
You can calculate the area of a circle with the formula: A = pi x radius2 If the 30 inches refers to the diameter, divide it by 2 to get the radius.
A circle with a radius of 30 feet has an area of 2,827.43 square feet.
30 inches; the radius of a circle is 1/2 its diameter.
The diameter of a circle is the distance across the circle passing through its center. In this case, the diameter of a 30-inch circle would be 30 inches. It is important to note that the diameter is always twice the length of the radius, which is the distance from the center to any point on the circle's edge.
Radius is 30 inches.
The radius is 30 inches.
