Radius = 1/2 of diameter = 19 centimeters.
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
The radius is the distance from the center of a circle to one edge. The diameter of a circle is the distance from one side to the other that must cross the center of the circle. The diameter is 2 times the radius. Dia = 2R therefore, 2*38 cm = 76 cm
12 inch diameter(also 6 inch radius).
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
V = Bh or V = πr^2h Since diameter is 6 cm, then radius is 3 cm. Substitute what you know into the formula and you have: 342 cm^3 = π[(3 cm)^2]h 342 cm^3 = π(9 cm^2]h divide by 9 cm^2 to both sides 38 cm = πh divide by π to both sides 38 cm/π = h or h = 38 cm/π h ≈ 12 cm
38: the diameter of a circle is twice its radius.
The radius is one-half of the diameter. Hence, the radius of a 76 in diameter circle is 38 in.
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 circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
The radius is the distance from the center of a circle to one edge. The diameter of a circle is the distance from one side to the other that must cross the center of the circle. The diameter is 2 times the radius. Dia = 2R therefore, 2*38 cm = 76 cm
Diameter: 2 times 19 = 38 mm
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
12 inch diameter(also 6 inch radius).
12 inch diameter(also 6 inch radius).
That depends on what is meant by 38 mi but the circumference of any circle is 2*pi*radius or diameter*pi
Circumference = 2*pi*radius or diameter*pi
If diameter is 38, then the radius is half of that or 19 inches.. Now the area is Pix192
