Use the formula for the area of a circle: A = pi x r2, where "r" is the radius.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
168.56 square inches
38: the diameter of a circle is twice its radius.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
Radius = 1/2 of diameter = 19 centimeters.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
The outline of a circle of radius 9.5/pi cm
Area = 1,134.1 units2
168.56 square inches
38: the diameter of a circle is twice its radius.
If diameter is 38, then the radius is half of that or 19 inches.. Now the area is Pix192
It is: 19/2 = 9.5mm
The circumference is Pix38 or about 119.
27 * 19 = 513 cm2
