Answer:
Step-by-step explanation:
The equation for a circle in standard form is , where h and k are the coordinates of the center. Our center has an h value of -2 and a k value of -3 with an r value of 3. Fitting those values into our standard form of a circle we have . Subtracting a negative is the same as adding, and squaring the right side gives us 9, so the equation is . Third choice from the top.
Answer:
The difference in area between the trapezoid and the rectangle is 10 in²
Step-by-step explanation:
The dimensions of the trapezoid are given as follows;
Base 1, a = 12 in
Base 2, b = 10 in
Height, h = 10 in
Area, A of trapezoid;
The dimensions of the rectangle are given as follows;
Base = 12 in
Height = 10 in
Area, A of rectangle;
Base × Height = 12 × 10 = 120 in^2
Therefore, the difference in area between the two packages is found as follows;
Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²
The difference in area between the trapezoid and the rectangle = 10 in².
