In geometry, the half circle is referred to as the semicircle. The semicircle is made by dividing a whole circle along its diameter. Alternatively, a semicircle could also be an open arc where a curved line represents half a circle's circumference but with no straight diameter line closing its area.
Know MoreA semicircle's area is always half the area of the original circle that is divided. To measure the area of a semicircle, pi needs to be multiplied to the square of the semicircle's radius before being divided into two. The perimeter of the semicircle is measured by adding the multiplication result of pi with the radius of the semicircle and twice the radius of the semicircle.
Learn more about ShapesThe area of a semicircle is (?*R*R)/2. This means the radius of the semicircle is squared, multiplied by the constant pi, then divided by 2.
Full Answer >A kite is a quadrilateral, a shape with four straight, flat sides, that has two pairs of sides where the two adjacent sides, the ones that meet, are equal in length. The two angles in a kite where the sides with different measurements meet are identical. The other two angles may or may not be identical.
Full Answer >To find the arc of a circle, divide the angle subtended at the center of the arc by 360 degrees, then multiply the answer by the circumference of the circle. You need to know the value of pi and must have a protractor to complete this task.
Full Answer >According to the U.S. Postal Service, the proper abbreviation for "circle" in addresses is "CIR." Although "CIRC," "CIRCL," "CRCL" and "CRCLE" are commonly used, "CIR" is the standardized abbreviation preferred for all mail.
