To find the area of a circle, you do π × diameter (in this case 10). They have told you to use 3.142 as π, so you do 3.142 × 10 = 31.42. Because it's a semi-circle, you need to halve 31.42 to get 16.21, which is the answer
24-3x=-27
-24 -24
-3x=-51
— —
-3 -3
X=17
X=60 and y=20
x and y can be many things that answers the question to 120
