Formula of Area of a Semicircle
The universal formula to calculate the area of a semicircle is given below
Area = 1/2 (π * r2)
where, r is the radius of the semicircle.
Steps to Get Semicircle Area
The following are the instructions and guiding principles that are useful to find the semicircle area. Have a look at the below section and follow them.
- Let us take the radius or diameter of a semicircle.
- We already know that, diameter is double radius. So, radius becomes half of the diameter.
- Formula to compute the semicircle area = 1/2 (π * r2)
- Substitute the radius value in the above formula.
- Work on the math calculations to get the result.
Example of Finding the Area of a Semicircle
Question: Find the area of a semicircle of radius 7 cm?
Solution:
Given that radius of semicircle = 7 cm
Area of semicircle = 1/2 (π * r2)
= 1/2 (π * 72) = 1/2 (22/7) x 7 x 7
= 11 x 7
Area = 77 cm
