A circle with radius 2 sits inside a 7×11 rectangle. What is the area of the shaded region?
We draw the problem in the picture attached. The picture is not drawn to scale!
In order to find the shaded area, you need to subtract the area of the circle from the area of the rectangle.
Therefore:
A(rectangle) = b·h = 11×7
= 77 u²
A(circle) = π·r² = 3.14 · 2²
= 3.14 · 4
= 12.56 u²
A(shaded) = A(rectangle) - <span>A(circle)
= 77 - 12.56
= 64.44 u²
Hence, the shaded figure has an area of 64.44 square units.

Answer:
$7,986.25
Step-by-step explanation:
We can use the following formula to solve:
<em>P = principal value</em>
<em>r = rate (decimal)</em>
<em>t = time (years)</em>
<em />
First, change 15% into a decimal:
15% -> -> 0.15
Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:
Your car would be worth $7,986.25
