The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
The area of a circle has the formula πr2 This means pi x radius squared. If the radius is 15. Square 15- 15x15. Multiply it by pi(3.14159265) Answer is 706.9mm2
The radius of a circle with an area of 706.50 square inches is: 15 inches.
706.9 cm2
If I remember correctly Area of a circle is... PIE multiplied by the RADIUS squared. If this is so.... 15 is the radius and... The sum of 15 x 15 should be multiplied by pie (3.1415 or what ever it is). Use a calculator to get to the nearest tenth.
