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
The term "radius" typically refers to the distance from the center to the edge of a circle or sphere. If you are asking for the radius of a circle with an area of 19 square units, you can use the formula ( A = \pi r^2 ) to find the radius ( r ). Solving for ( r ), you get ( r = \sqrt{\frac{19}{\pi}} ), which is approximately 2.47 units. If you meant something else by "radius of 19," please provide more context.
The circumference is Pix38 or about 119.
It is: 19/2 = 9.5mm
