Answer:
113.143 cm²
Step-by-step explanation:
Radius=diameter/2=12/2=6 cm
Now
Area of a circle=πr²
=(3.16)(6)²
=(3.16)(36)
=113.143 cm²
Answer:
54
Step-by-step explanation:
Diagonals are perpendicular so
2x+ 90 + 3x = 180 since this forms a triangle
Combine like terms
5x+ 90 = 180
Subtract 90 from each side
5x +90-90 =180-90
5x = 90
Divide each side by 5
5x/5 = 90/5
x =18
We want to find Angle ABD
ABD = 3x = 3*18 = 54
The answer would be -5 because:
-6-(-1)
Keep Change Flip
-6 + 1
Different signs Subtract..so the answer would be 5 but then you add the negative to it because -6 is greater than the positive 1
