Guys I need help pleeeaassee i'm trying to graduate! Find the area of the shaded portion in the square. (assuming the central po
int of each arc is the corresponding corner)
1 answer:
Area of the square = (side)*(side)
Area of the square = (2)*(2)
Area of the square = 4
Area of the quarter circle = (area of full circle)/4
Area of the quarter circle = (pi*r^2)/4
Area of the quarter circle = (pi*1^2)/4
Area of the quarter circle = (1/4)*pi
The top shaded region is found by taking the area of the square and subtracting off the area of the quarter circle, so we get,
top shaded region area = (area of square) - (area of quarter circle)
top shaded region area = (4) - (1/4pi)
The two shaded regions are congruent so we can double the area of the top region to get the total overall area.
Total shaded area = 2*(top shaded region area)
Total shaded area = 2*(4 - pi/4)
Total shaded area = 8 - pi/2
Total shaded area = 8 - (1/2)pi
Therefore, the final answer is
Area of the square = (2)*(2)
Area of the square = 4
Area of the quarter circle = (area of full circle)/4
Area of the quarter circle = (pi*r^2)/4
Area of the quarter circle = (pi*1^2)/4
Area of the quarter circle = (1/4)*pi
The top shaded region is found by taking the area of the square and subtracting off the area of the quarter circle, so we get,
top shaded region area = (area of square) - (area of quarter circle)
top shaded region area = (4) - (1/4pi)
The two shaded regions are congruent so we can double the area of the top region to get the total overall area.
Total shaded area = 2*(top shaded region area)
Total shaded area = 2*(4 - pi/4)
Total shaded area = 8 - pi/2
Total shaded area = 8 - (1/2)pi
Therefore, the final answer is

Determine the items Lonnie can afford
To solve this question, we make use of trial by error method by taking the options one at a time:
Option 1: 6 movies and 4 video games
<em>This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.</em>
<em />
Option 2: 14 movies and 7 video games
<em>This option can not be considered because the cost of purchase is greater than Lonnte's worth of Gift card.</em>
<em />
Option 3: 2 movies and 10 video games
<em>This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.</em>
<em />
Option 4: 8 movies and 6 video games
Hence, the correct option is <em>8 movies and 6 video games </em>
