72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
Answer: The answer would be D. 64
Step-by-step explanation: Understanding that the question noted that the second rectangle was dilated from PQRS, which has a perimeter of 16. With the coordinates of point P for the first rectangle being (2,0.5) whilst the second rectangle has point P at (8,2). To figure out the perimeter, divide point P from the second rectangle with point P from the first. The result would be 4. Thus, the scale factor is 4, which you then multiply the perimeter of PQRS by, which was 16. 16 times 4 equals 64.
<h3>Area of shaded region is 21.5 square centimeter</h3>
<em><u>Solution:</u></em>
The area of the shaded region is equal to the area of the square minus the area of the circle
<em><u>
Find the area of the square</u></em>

Where, "a" is the length of each side
From given figure in question,
a = 10 cm

<em><u>Find the area of circle
</u></em>
The area of the circle is given as:

Where, "r" is the radius of circle
Diameter = 10 cm

Thus,

<em><u>Find the area of the shaded region</u></em>
Area of shaded Region = Area of Square - Area of Circle
Area of shaded Region = 100 - 78.5 = 21.5
Thus area of shaded region is 21.5 square centimeter
Solve the equation for x:
4x+12=48
Subtract 12 from both sides: 4x=36
Divide 4 from both sides to isolate x: x=9
