The formula for the area of a circle is a = <span>πr², r being the radius.
To tackle this problem, find the area of the square and then subtract the area if the circle:
Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314
Area of square - area of circle = 400 - 314 = 86 m²
Hope this helps!

Dilation always preserves angle measures, the given statement best explains why the dilation of a triangle produces a similar triangle
<u>Step-by-step explanation:</u>
The dilation (similarity transformations) varies the size of the figure. This requires a midpoint and a scale factor k. The k value finds whether it is an increase or decrease.
- If | k |> 1, the dilation is an extension.
- If | k | <1 it is reduction.
The absolute value of k determines the size of the new image relative to the size of the original image. If the k is positive, the new and original image is on the same side of the center.
If k is negative, they are on both sides of the center. Its own image is always at the center of development. This support angle size, point equality, and collinearity. Does not maintain distance. In simple, dilation always give similar figures.
Answer:
y = -5x + 39
Step-by-step explanation:
Plug either ordered pair into the Point-Slope Formula FIRST, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>then convert to Slope-Intercept Form by moving whichever term is nearest to <em>y</em><em>,</em><em> </em>over to the right side of the equivalence symbol to get the above answer.
