They have the same slope only the y intercept is different. They will never intercept.
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
The answer is “like” terms.
You add common terms together to get variables by themselves.
Answer:
Step-by-step explanation:
The shaded area is the difference of the total area and the white triangle.
The white triangle has base of 9 cm and height of 4 cm.
<u>Its area is:</u>
<u>Area of rectangle:</u>
<u>The shaded area:</u>
The estimated sum is 440
70+130+140+100
