Webb1 mars 2024 · Given: Perimeter of semicircular protractor= 72 cm To Find: Diameter of the protractor. Solution: The formula of the perimeter of semicircle= πr + 2r, where r is the radius ∴ According to the question, πr + 2r = 72 cm. ⇒r (π + 2) = 72 cm. Putting the value of π as 3.14 in the sum,
Webb9 mars 2024 · To determine the perimeter of a semicircle: Write down the radius r. Multiply the radius by π+2: r × (π+2) ≈ 5.14159 × r. The result is the perimeter of your … WebbWhen a circle is cut along its centre line or the diameter, the resultant figure gives us two congruent semicircles. In other words, a semi-circle is exactly half of a circle. The perimeter, i.e., the length of the boundary of a semicircle is calculated by the formula (d+ rπ), where d is the diameter, and r is the radius of the semicircle.
WebbA perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.
