Diameter and radius
Yes, but the only part is less than half of the state of Alaska.
half a circle is a semicircle half a ball is a hemisphere does that help?
If the half circle is on its flat side, the radius is its height. If the straight part of the half-circle is vertical, the radius is its width.
An arc. The arc covering less than half the circumference is called a minor arc; the arc covering more than half is called a major arc.
From the center to an outside part. Half the diameter
With a ruler, or other suitable length measuring device. Measure the diameter (the widest part of the circle). The radius is half the diameter.
it represents the radius because radius is half the diameter and diameter is across the whole circle
One half of a circle plus two tenths of a circle equals 0.5 + 0.2 = 0.7 of a circle. To convert this into a percentage, multiply by 100: 0.7 * 100 = 70%. Therefore, one half of a circle plus two tenths of a circle is 70% of a whole circle.
The number of degrees in a circle is always 360.The number if degrees in a part of a circle is that same part of 360.In 74.2% of a circle, there are 74.2% of 360 degrees.
By calculating the areas of the rectangular bottom part, (LxW) , and then using pi to find the area of the top rounded part. (3.14 x Radius x Radius divided by 2) - if the rounded section is half a circle
The length of the curved part of the semicicle is π*d/2 where π is the transcendental number approximated by 3.14159 and d is the diameter. The length of the straight part of the semicircle is, of course, d.
Part of the circumference of a circle less than 180 degrees
