Area of a Semi Circle: (pi x r^2)/2
3.14 x 2^2
3.14 x 4 = 12.56
12.56/2 = 6.28
Therefore, the area of a semi-circle is 6.28.
Answer:
The area of semi-circle is 2π units²
Step-by-step explanation:
Given that the formula of area of circle is, Area = π×r² where r represents radius of circle. Then, you have to substitue the value of radius into the formula :
Let r = 2 units,
A = π×2²
= 4π units²
The question says it is a semi-circle so you have to divide it by 2 :
A = 4π ÷ 2
= 2π units²
