The diameter of a semicircle is 2 centimeters. What is the semicircle's radius?
The radius of a circle is half of its diameter. Therefore, the radius of a semicircle is half of the diameter of the corresponding circle.
In this case, the diameter of the semicircle is 2 centimeters. The corresponding circle would have a diameter of 4 centimeters.
The radius of the circle (and thus the semicircle) is half of the diameter:
radius = 4 cm / 2 = 2 cm
Therefore, the radius of the semicircle is 2 centimeters.
The diameter of a semicircle is half the length of the full circle that it is a part of. So, if the diameter of the semicircle is 2 centimeters, the radius of the semicircle would be half of that. So, the radius of the semicircle is 1 centimeter.
To find the radius of a semicircle with a given diameter, you can divide the diameter by 2.
In this case, the diameter is given as 2 centimeters. So, we can calculate the radius as:
Radius = Diameter / 2
= 2 cm / 2
= 1 cm
Therefore, the radius of the semicircle is 1 centimeter.
