Answer 1

Answer:

1.57

Step-by-step explanation:

The formula for the area of a semicircle is

π (pi) * r^2 /2

The Diameter of your semicircle is 2, and the radius is half of the diameter, so the radius (r) of the semicircle is 1.

3.14 * 1^2 /2

Solve 1^2

3.14 * 1 / 2

According to PEMDAS, you solve the Multiplication first.

3.14 * 1 = 3.14

Now divide with your dividend above.

3.14 / 2 = 1.57

Therefore, your answer is 1.57

Answer 2

1.57 is the answer bc 3.14 is pi times 1 is itself so pi/3.14 over 2
