The Areas of each of the composite shapes are;
1) A = 30 m²
2) A = 20 yd²
3) A = 615.4 km²
4) A = 23 cm²
5) A = 168 m²
6) A = 86.3 m²
<h3>How to find the area of regular shapes?</h3>
1) Area of parallelogram = bh
A = 6 * 5
A = 30 m²
2) Area of Triangle = ¹/₂bh
A = ¹/₂ * 10 * 4
A = 20 yd²
3) Area of circle is;
A = πr²
A = 3.14 * 14²
A = 615.4 km²
4) Area of this composite figure is;
A = Area of Triangle - Area 0f rectangle
A = (¹/₂ * 13 * 10) - (7 * 6)
A = 65 - 42
A = 23 cm²
5) Area of composite figure is;
A = 2(¹/₂ * (16 + 8) * 3) + (16 * 6)
A = 72 + 96
A = 168 m²
6) Area of composite figure;
A = ¹/₂ * (15 + 8) * 7.5
A = 86.3 m²

I finished the test and here's the answer~!
3x+5y=25.75
8x+2y=29.00
So I first got what x is equal too.
8x+2y=29 8x+2y-2y=29-2y 8x=29-2y 8x/8=29/8-2y/8 x=3.625-0.25y
Next substitute x for the equation.
3(3.625-0.25y)+5y=25.75
10.875-0.75y+5y=25.75
10.875-10.875+4.25y=25.75-10.875
4.25y/4.25=14.875/4.25
y = 3.5
Now substitute y for 3.5.
8x+2(3.5)=29
8x+7-7=29-7
8x/8=22/8
x = 2.75
The price of a flower bouquet would be $2.75. Don't worry I got this question correct. :)
Answer:
c. 
Step-by-step explanation:
We have been given that the area in square units of an expanding circle is increasing twice as fast as its radius in linear units
We will use derivatives to solve our given problem.
We know that area (A) of a circle is equal to
.
Let us find derivative of area function with respect to time.

Bring out constant:

Using power rule and chain rule, we will get:

Here
represents change is radius with respect to time.
We have been given that area of an expanding circle is increasing twice as fast as its radius in linear units. We can represent this information in an equation as:





Therefore, the radius is
and option 'c' is the correct choice.
Answer:
The answer is
<h2>r =4 ft</h2>
Step-by-step explanation:
Area of a circle is given by πr²
Where r is the radius
From the question
Area = 64 ft²
So the radius is
64 = πr²
Divide both sides by π

Find the square root of both sides

r = 4 ft
