Find the area of the circle below, to the nearest tenth. Use 3.14 for t.
Answers
Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
[tex]A=\pi r^2[/tex] ...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.
[tex]r=\dfrac{9}{2}[/tex]
[tex]r=4.5[/tex]
Substituting [tex]r=4.5, \pi =3.14[/tex] in (i), we get
[tex]A=(3.14)(4.5)^2[/tex]
[tex]A=(3.14)(20.25)[/tex]
[tex]A=63.585[/tex]
[tex]A\approx 63.6[/tex]
Therefore, the area of the given circle is 63.6.

17. A glider lands 20 miles east and 6 miles south from where it took off. The result of the trip can
be described by the vector (20. -6).
What is another description of this vector using distance (for magnitude) and direction?
O about 17 miles at 21° south of west
about 17 miles at 21° south of east
about 21 miles at 17° south of west
O about 21 miles at 17° south of east
Answers
Answer:d
Step-by-step explanation:
The correct description of the vector (20, -6) using distance (for magnitude) and direction is: about 21 miles at 17° south of west.
To determine this, we can use the Pythagorean theorem to find the magnitude or length of the vector.
That implies,
[tex]\sqrt{(20^2 + (-6)^2) }[/tex]= 21 miles.
The direction of the vector can be determined using trigonometry.
Since the glider moved 20 miles east (positive x-axis) and 6 miles south (negative y-axis), the angle is measured from the positive x-axis in a counterclockwise direction.
The angle can be found as arctan((-6)/(20)) ≈ -16.70 degrees. Since the angle is south of west, we take the absolute value, resulting in approximately 16.70 degrees.
Therefore, the description is about 21 miles at 17° south of west.
This description provides the magnitude (distance) and direction of the glider's trip accurately.

The formula for the area of the triangle is:
[tex]\displaystyle A=24x^2[/tex]
When x = 3, the area is 216 square centimeters.
When x = 2.4, the area is 138.24 square centimeters.
And when x = 5, the hypotenuse of the triangle is 50 centimeters.
Step-by-step explanation:
We are given a right triangle with a height of 8x and a base of 6x.
The area of a triangle is given by the formula:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
So, by substitution:
[tex]\displaystyle A=\frac{1}{2}(8x)(6x)=24x^2[/tex]
When x = 3, the area will be:
[tex]\displaystyle A(3)=24(3)^2=216\text{ cm}^2[/tex]
And when x = 2.4, the area will be:
[tex]A(2.4)=24(2.4)^2=138.24\text{ cm}^2[/tex]
When x = 5, the height will be 8(5) = 40 cm and the base will be 6(5) = 30 cm.
By the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
So:
[tex](40)^2+(30)^2=c^2[/tex]
The hypotenuse will be:
[tex]c=\sqrt{1600+900}=\sqrt{2500}=50\text{ cm}[/tex]

A rectangula rprism with a volume of 4 cubic units is filled with cubes with side lenghts of 1/3 units. How many 1/3 unit cubes does it take to fill the prism
Answers
Answer:
36 cubes
Step-by-step explanation:
A rectangula prism with a volume of 4 cubic units is filled with cubes with side lenghts of 1/3 units.
Volume of cubes = (side length)³
Volume = (1/3)³
= 1/9 cubic units
Therefore, the number of 1/3 unit cubes it takes to fill the prism is calculated as:
= 4 cubic units ÷ 1/9 cubic units
= 4 × 9/1

Divide both sides of the top equation by 3 C. Divide both sides of the bottom equation by 2 D. Multiply both sides of the bottom equation by 3
Answers
Explanation:
By multiplying the top equation by 3, you now have
12x + 6y = 12
12x + y = 22
To completely solve the equation, you multiply the whole bottom equation by -1.
12x + 6y = 12
-12x - y = -22
The -12x and 12 x cancel each other out.
6y = 12
-y = -22
______
5y = -10
y = -2
Now that you have the value of y, you can plug it into the original equation.
4x + 2y = 4
4x + 2(-2) = 4
4x - 4 = 4
4x = 8
x = 2
So, your final answer is (2, -2).

Walter needs new grass in the circular pen for his chickens. The pen has 308 feet of fencing. What is the area of the pen?
Answers
Answer: 7546feet²
Step-by-step explanation:
Since the pen has 308 feet of fencing, this is the perimeter of the circular pen and we can get the raduus which goes thus:
Circumference of a circle = 2πr
2πr = 308
2 × 22/7 × r = 308
44/7 × r = 308
r = 308 × 7/44
r = 49
Therefore, area of the circular pen will be:
= πr²
= 22/7 × 49 × 49
= 7546feet²
