Area of a circle = PI x r^2
Area = 3.14 x 11^2
Area = 3.14 x 121
Area = 379.94 square cm.

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² + 10x - 6
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute: f(-5) = -(-5)² + 10(-5) - 6
- Exponents: f(-5) = -(25) + 10(-5) - 6
- Multiply: f(-5) = -25 - 50 - 6
- Subtract: f(-5) = -75 - 6
- Subtract: f(-5) = -81
Since the rectangles are similar. The ratio of their sides will be the same.
So, we can write:
Therefore, the left side of the bigger rectangle will be 12 units in length.
Answer:
9.29 acres
Step-by-step explanation:
2 2/7 = 15/7
4 1/3 = 13/3
(15/7) * (13/3) = 195/21 = 9.29 acres
Answer:
Line W'X' is 4 times longer than line WX.
Step-by-step explanation:
When we dilate a figure by a scale factor, the side length increases by that scale factor. If the length was 1 before the dilation, and the scale factor is 2, the length would be 2 after the dilation because 1*2=2. Assuming that WX and W'X' are sides of the figure because no image was provided, the dilated side should be 4 times longer.
