A circle with a radius of 19 cm has an area of 1,134.11 square cm.
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.
Use the formula for the area of a circle: A = pi x r2, where "r" is the radius.
38: the diameter of a circle is twice its radius.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
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.
Area = 1,134.1 units2
Use the formula for the area of a circle: A = pi x r2, where "r" is the radius.
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 circumference is Pix38 or about 119.
It is: 19/2 = 9.5mm
Radius = 1/2 of diameter = 19 centimeters.
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
If the 19' is referring to the circumference of a circle then the diameter is approx. 6.0479'. 19÷3.1416=approx. 6.0479 If the 19' is referring to the radius, (from center of the circle to the outside edge), then the answer is 38'. diameter= radius X 2. 19X2=38
