Just add a similar triangle from the opposite side
Then what happens
- Hypotenuse of this triangle becomes common and diagonal of the rectangle.
Now
Area

- Area of triangle=20/2=10units^2
Answer:
4-3x over x or 4-3x/x
I'm not sure. but I hope it can help you:))
2 5/8 × 4 = 10 1/2
Charlie does not have enough wood because 10 1/2 is also equal to 10 4/8 and Charlie only has 10 3/8
hope this helped
Answer:
pi × 18cm^2
Or approximately,
56.52cm^2 (using 3.14 for pi)
or
56.5487cm^2 (using pi button on calculator)
Step-by-step explanation:
Area of a circle is pi times [radius squared].
All circles are 360°.
Problem can be solved by finding area of whole circle, and then using ratios.
Whole Circle: area = pi × (9cm)^2 = pi × 81cm^2
80° / 360° = Area[shaded] / (pi × 81cm^2)
pi × 18cm^2 = Area[shaded]
