Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle

So therefore, i think it is 33. Sorry if its confusing B(
Answer:
x >-14
Step-by-step explanation:
To solve the inequality, we need to isolate the variable, x
-4x -6 <50
Add 6 to both sides
-4x <56
Divide both sides by -4
Since we divided by a negative number, we must flip the inequality sign
x <-14
Flip the inequality sign
x> -14
