Radius of circle: 132/2pi = 21cm to the nearest integer
The radius of any circle is the straight line distance from the centre of the circle to any point on the circumference of the circle. The radius being 21 cm makes no difference to the definition of the radius; it just means that the straight line distance from the centre of that circle is 21cm away from any point on the circumference of that circle. The radius of a circle with a radius of 21 cm is 21 cm.
A = 346.36 cm2
The area of a circle of radius 21 is 1386
A = 1,385.4 cm2
The area of a circle is calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Plugging in the radius of 21cm into the formula, we get A = 3.14159 x (21)^2 = 1385.44 square centimeters. Therefore, the area of a circle with a radius of 21cm is 1385.44 square centimeters.
