Well, darling, if the circle has a diameter of 3.8 cm, then the radius would be half of that, which is 1.9 cm. It's as simple as cutting a cake in half, but without the calories. So, grab a ruler and measure that radius like the sassy math pro you are!
The radius of a circle is half the diameter, and the diameter is the distance across the circle passing through the center. So, if the circle has a diameter of 3.8 cm, the radius would be half of that, which is 1.9 cm.
Radius in from the center of circle or sphere, so a radius of 3.8 cm is a diameter of 7.6cm and circumference 23.8 cm (or 24 cm).
Or
If you mean 3.8 is the diameter (width), then radius is half (1/2) which equals 1.9 cm and circumference of 11.9 cm (12cm).
Or
If circumference 3.8 then radius is 1.2cm and area is 1.152cm.
I hope this answers your question.

If the radius the radius of a circle is 38 cm what is the length of its diameter and how?
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
What is the diameter of 19cm radius?
The diameter of a circle is twice the length of its radius. So, to find the diameter of a circle with a radius of 19 cm, you would multiply 19 cm by 2. This gives you a diameter of 38 cm.
What is the radius of a 2 cm circle?
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
What is the radius of a circle with a 6.2 cm diameter?
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
What is the circumference of a circle if the if the radius is 6 cm?
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
If the radius the radius of a circle is 38 cm what is the length of its diameter and how?
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
What is the radius of a circle that is 7.1 cm?
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The circumference of a circle is 60 cm what is the radius of the circle?
The radius of the circle is: 9.549 cm
What is the radius of a 2 cm circle?
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
If a circle has a circumference of 16 cm then what is the radius of the circle?
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
The diameter of a circle is 12 cm what is its radius?
If the diameter is 12 cm the radius is 6 cm.
What is a circle's diameter if the radius is 7 cm?
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
What is the radius of a circle with a 6.2 cm diameter?
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
What is the circumference of a circle if the if the radius is 6 cm?
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
