The first thing you do is find the area of the rectangle, which is l*w or 9*4 = 36. Then you find the area of the circle, which is pi*r^2 or pi*2^2 or 4*pi (do not combine pi and 4 yet). Lastly, you would subract the area of the circle from the area of the rectangle. It would be 36-4*pi, which equals about 23.43 ft.
Answer:
a
Step-by-step explanation:
With the help of the given equation, we know that the automobile is worth $12528.15 after four years.

What are equations?</h3>
- A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
- a formula that expresses the connection between two expressions on each side of a sign.
- Typically, it has a single variable and an equal sign.
- Like this: 2x - 4 Equals 2.
- In the above example, the variable x exists.
So, the equation of depreciation: y = A(1 - r)∧t
The current value is y.
A is the initial cost.
r is the depreciation rate.
t is the time in years, and
In four years, we must ascertain the present value.
Now,
y = $24000(1 - 0.15)⁴
y = 24000(0.85)⁴
y = 24000 × 0.52200625
y = 12528.15
Therefore, with the help of the given equation, we know that the automobile is worth $12528.15 after four years.

Complete question:
The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
Answer:
55degrees
Step-by-step explanation:
Let the other angles of the triangle are x, x degrees. Since the sum of angles in a triangle is 180degrees, hence;
<A + <B+ <C = 180
x + 70 + x = 180
2x+70 = 180
2x = 180 - 70
2x = 110
x = 110/2
x = 55
SInce <A is equal to x, hence <A is 55degrees
