The volume of the fish tank having height 38 inches and diameter 26 inches = 20,165.08 [tex]inch^{3}[/tex]
What is Volume of cylinder?The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it.
The height of the fish tank = 38 inches
Diameter = 26 inches
Radius of fish tank = 13 inches
Volume of the fish tank =[tex]\pi* r^{2}*h[/tex]
= 3.14 x 13 x13 x 38
= 3.14 x 169 x 38
= 20,165.08 [tex]inch^{3}[/tex]

Answer: 226.56 m²
Step-by-step explanation:
We need to find the area of three rectangles and two triangles.
The triangles: 34.56 m²
A = [tex]\frac{B*H}{2}[/tex]
-> Since they are both congruent, we will skip dividing by two
A = B * H
A = 7.2 * 4.8
A = 34.56 m²
The rectangles: 192 m²
A = L * W
-> We have two that are congruent, and one that is not
A = 10 * 6 * (2, since there are two)
A = 120 m²
-
A = L * W
A = 7.2 * 10
A = 72 m²
-
72 m² + 120 m² = 192 m²
Total surface area:
34.56 m² + 192 m² = 226.56 m²

Find the Area of the figure below, composed of parallelogram and two semicircles.
Round to the nearest tenths place.
Answer:
622.13 square units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of circle
Note: 2 semicircles = 1 full circle
Area of the figure = a*h + πr²
Where,
a = 22
h = 11
r = ½ of 20 = 10
Plug in the value into the equation
Area = 22*11 + π*11²
Area = 242 + π*121

For the target below an archer randomly shoots an arrow which hits the target, what is the theoretical probability the arrow will hit the small square on the upper left? Assume all squares are the same size. Round to the nearest tenth of a percent.
A. 9.8%
B. 2.5%
C: 1.0%
The theoretical probability that the arrow will hit the small square on the upper left is approximately 9.8%. (Option A)
To determine the theoretical probability, we first need to calculate the areas involved. Let's start by finding the area of the entire circular target. The formula for the area of a circle is given by A = π * r², where 'r' is the radius. Plugging in the given radius (36 inches) into the formula:
A_circle = π * (36 inches)² ≈ 4069.73 square inches.
Next, we need to calculate the area of the small square in the upper left corner. Since the square is positioned at a corner of the circle, it forms a quarter of a circle. The area of this quarter circle can be calculated as follows:
A_quarter_circle = ¼ * A_circle. = ¼ * 4069.73 = 1017.43
Now, let's find the area of the square. The formula for the area of a square is A_square = side², where 'side' is the side length. Plugging in the given side length (5 inches) into the formula:
A_square = (5 inches)² = 25 square inches.
However, there are four identical squares inside the quarter circle, so the total area of all the squares combined is:
Total_Area_squares = 4 * A_square.
Now, to calculate the probability of hitting the small square in the upper left corner, we divide the area of that square by the area of the quarter circle:
Probability = (A_square / A_quarter_circle) * 100. = 25 / 1017.43 * 100 = 9.8%.
Hence the correct option is (a).

Step-by-step explanation:
Area of a triangle = 1/2 × base × height
Given:
base = 20 inheight = 14 inSubstituting the given values into the formula:
⇒ Area = 1/2 × 20 × 14
= 140 in²
Answer as a decimal rounded to the nearest hundredth = 140.00 in²
Answer:
140 square inches
Step-by-step explanation:
Formula to find the area of a triangle is A = 1/2 × b × h.
So plug in the numbers
A= 1/2 x 20 x 14
A= 20 x 14 / 2
A = 280/ 2

Given that tangent squared theta = three-eighths, what is the value of secant theta? Plus-or-minus StartRoot eight-thirds EndFraction Plus-or-minus StartRoot eleven-eighths EndFraction Eleven-eighths Eight-thirds
Using a trigonometric identity, considering the given value of the tangent of theta, the secant of the same angle is given by:

How is the tangent related to the secant?According to the following identity:
[tex]\sec^2{\theta} = 1 + \tan^2{\theta}[/tex]
In this problem, the tangent squared is given as follows:
