How to calculate the Area of Semicircle ?
Using Radius:
The area (A) of a semicircle with radius (r) can be calculated using the formula:
Using Diameter:
Alternatively, if the diameter (d) is known, the area can be calculated as:
Examples:
Given radius, r = 7 cm
Using the formula:
Area = 76.97 cm2
Given radius, r = 5 cm
Using the formula:
Area = 39.26 cm2
Given diameter, d = 10
Using the formula:
Area = 39.26 cm2
