Area = pi*302 = 2827.433 square inches to 3 decimal places
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.
If you are asking about a circle with a circumference of 30" than it would be 9.5".I you mean a radius of 30" than it would be 60".If you mean an area of 30" than it would be 19".
Radius is 30 inches.
The radius is 30 inches.
900 cm
A circle with a radius of 30 meters has an area of 2827.43 square meters.
Area of a circle = pi*radius squared
2 * area of circle + circumference * height 2 * pi*r^2 + 2pi*r * h 2pi*8^2 + 2pi*8*30 128pi + 480pi 608pi
