Area of a semicircle | CBSE Class 10th Maths Formula note
- The area occupied by the semicircle is the territory within the semicircle's edge.
-Half of a circle is a semicircle. As a result, the area of a semicircle is half that of a circle.
– The area of a semicircle can be determined using both the radius and diameter.– The area of a circle is πr2
How do you calculate Area of semicircle?
- The formula to calculate the area of a semicircle in terms of radius 'r' is πr2/2
How do you calculate Area of semicircle?
– The formula to calculate the area of a semicircle in terms of diameter is πd2/8.– Where ‘r’ is the radius– π is a constant whose value is 22/7 or 3.14.
Example: Find the area of a semicircle of radius 7cm.
Note:
– Semi-circle is one half of
a circle
– The area of a circle with radius ‘r’ is πr2
– The area of a semicircle
with radius ‘r’ is πr2/2
