Perimeter of semicircle formula

Semicircle Formulas Half a portion of any circle is known as a semicircle and is formed by cutting a whole circle along the diameter. Various parameters related to a semi-circle like a diameter, area, the perimeter can be calculated using semicircle formulas. The diameter of a circle divides the circle into two equal semicircles. The area of any semicircle is half of the area of a circle. Let us understand the semicircle formulas using solved examples in the following sections. What are Semicircle Formulas? The semicircle formulas include the formulas to calculate the area, Area of a Semicircle Formula Since we know that a semicircle is half a circle, the semicircle area will be half of the 2 where R is the radius of the circle. The Area of a semicircle formula = πR 2/ 2 square units. where, • r = R is the radius of a semicircle • Perimeter of a Semicircle Formula The • The circumference of a circle is C = πd or C = 2πr. • Using the value of C, we can determine the formula for the perimeter of a semicircle which is calculated as the sum of half of the circumference of the circle and diameter of a circle. • The perimeter of a semicircle formula = (πR + d) or (πR + 2R), or R(π + 2) units. where, • R = • π(pi) is 22/7 or 3.142 approximately, and, • d = Circumference of a Semicircle Formula The circumference of a semicircle is defined as the length of the arc around the semicircle. It is half of the circumference of a circle. The difference between the circumference and perime...
