The radius (r) is half of the diameter (d). Given: - Diameter (d) = 7 cm Using the formula: r=d2 Calculating: r=72=3.5cm Step 2: Use the formula for the perimeter of the semi-circle. The perimeter (P) of a semi-circle includes the curved part and the diameter. The formula...
Since a semi circle is half of a circle, the area of a semi circle will be half the area of a circle. Definition of semi circle: As the name suggests, a semi circle is half of a circle. If an arc of a circle with its two ends on the diameter of a circle cuts the circle, th...
