Answer:
1372 cubic ft.
Step-by-step explanation:
[tex]V=\frac{4}{3} \pi 7^3[/tex]
[tex]V=\frac{4}{3} \pi 343[/tex]
[tex]V=457\frac{1}{3} \pi[/tex]
Since pi is 3 to find the approximate answer, do:
[tex]V=457\frac{1}{3} (3)[/tex]
[tex]V=1372[/tex]
Hence, the volume of the sphere is approximately 1372 cubic ft.
Answer:
V = 1,372 ft³
Step-by-step explanation:
You have been given the equation necessary for calculating the volume of a sphere:
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.
radius = diameter / 2
radius = 14 ft / 2
radius = 7 ft
Now, you can plug this value into the formula and simplify to find the volume.
[tex]V = \frac{4}{3}\pi r^{3}[/tex] <----- Volume formula
[tex]V = \frac{4}{3} * (3) *r^{3}[/tex] <----- Plug 3 in for "π"
[tex]V = \frac{4}{3} * (3) * 7^{3}[/tex] <----- Plug 7 in for "r"
[tex]V = \frac{4}{3} * (3) * (343)[/tex] <----- Solve 7³
[tex]V = 1,372 ft^{3}[/tex] <----- Multiply all the terms together

Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.

4 miles per hour
Step-by-step explanation:Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
This creates the proportion [tex]\frac{12miles}{3hours}[/tex]So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
12/3 equals 43/3 equals 1So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

2. 572.56
3. 283.53
4.254.47
5. 63.62
6. 380.13
Step-by-step explanation:
do πr²
r = radius
if you have a diameter like question 4 divide by 2 and you get radius
Answer:
1. A = 660.52 square units. C = 91.11 units.
2. A = 572.56 square units. C = 84.82 units.
3. A = 283.53 square units. C = 59.69 units.
4. A = 254.47 square units. C = 56.55 units.
5. A = 63.62 square units. C = 28.27 units.
6. A = 380.13 square units. C = 69.12 units.
Step-by-step explanation:
The equations for Area and Circumference of a circle are as follows:
A = πr², where r is the radius.C = 2πr, where r is the radius.You are given the radius (or diameter) of each circle which can be substituted into the above equations for r. Diameter is the entire length across the circle through the center, which is equal to 2(r).
1. A = π(14.5)² = 660.5198. The area is approx. 660.52 square units.
C = 2π(14.5) = 91.106. The circumference is approx. 91.11 units.
2. A = π(13.5)² = 572.555. The area is approx. 572.56 square units.
C = 2π(13.5) = 84.823. The circumference is approx. 84.82 units.
3. A = π(9.5)² = 283.528. The area is approx. 283.53 square units.
C = 2π(9.5) = 59.690. The circumference is approx. 59.69 units.
4. Diameter = 18; 18/2 = 9 = r. So, A = π(9)² = 254.469. The area is approx. 254.47 square units.
C = 2π(9) = 56.548. The circumference is approx. 56.55 units.
5. r = 9/2 = 4.5. So, A = π(4.5)² = 63.617. The area is approx. 63.62 square units.
C = 2π(4.5) = 28.274. The circumference is approx. 28.27 units.
6. A = π(11)² = 380.132. The area is approx. 380.13 square units.
C = 2π(11) = 69.115. The circumference is approx. 69.12 units.
