Answer:
6.28 units²
Step-by-step explanation:
The formula for finding the area of a circle:
πr²
We are given r = 2. So,
π(2)²
12.56 units²
However, it is a semicircle. So, only half of this value is needed.
12.56/2 = 6.28 units²
Answer:
area =12.56
Step-by-step explanation:
area of a semicircle=(pi(r)^2)/2
(3.14(2)^2)/2
(3.14(4))/2
12.56/2
6.28
