6cm
0.6cm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
15mm. diameter is twice the radius
The radius if the circle is half of its diameter and so 30/2 = 15 mm
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
You've stated an impossible question. If a circle has a circumference of 94.2 cm, it has a diameter of 30 cm. If it has a diameter of 15cm, it has a circumference of 47.1 cm.circumference = 2 * pi * radius = pi * diameterIf you had stated the question correctly (changed circumference to 47.1 cm OR changed diameter to 30 cm OR changed "diameter" to "radius"), then the answer would be:pi = circumference / diameter = (e.g.) 94.2 cm / 30 cm
30 centimeters is.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
just in case 1/2 of the diameter
The circumference of a circle with diameter of 30 centimeters is: 94.2 cm (diameter x Pi = circumference).
15mm. diameter is twice the radius
Radius = 1/2 of the diameter = 30
Diameter = Radius*2 = 30 cm.
The radius if the circle is half of its diameter and so 30/2 = 15 mm
the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46
Radius = 1/2 of the diameter = 30 units
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
30 inches; the radius of a circle is 1/2 its diameter.
