A circle has 3.8 cm What is the radius?

Answer 1

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!

Answer 2

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.

Answer 3

Oh, dude, you're hitting me with some math here. So, the radius of a circle is half of its diameter, right? And since you're telling me the diameter is 3.8 cm, the radius would be half of that, which is 1.9 cm. Easy peasy, lemon squeezy!

Answer 4

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.
