A circular pen has circumference of 77.5 feet. Approximate π to 3.14 and estimate how many sheep could be safely kept in the pen if each sheep needs at least 45 square feet.
Answer:
10 sheep
Step-by-step explanation:
First, we have to determine the area of the circular pen.
Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]
But,
Circumference of a circle = 2[tex]\pi[/tex]r
So that,
77.5 = 2 x 3.14 x r
77.5 = 6.28r
r = 12.34
Radius of the pen is 12.34 feet.
Thus,
Area of the pen = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](12.34)^{2}[/tex]
= 478.15
Area of the pen = 478.15 square feet
Number of sheep that can be safely kept in the pen = [tex]\frac{478.15}{45}[/tex]
= 10.63
The number of sheep that can be safely kept in the pen is 10.

What are the ratios for SIN A and COS A
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=Opposite over Hypotenuse
Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.
Which of the following is the correct scale?
1:72
1:12
1:144
5:60
Answer:
1:144
Step-by-step explanation:
if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches
Answer:
1:144 inches

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?
Answer:
10
Step-by-step explanation:
You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9
The height the 15 ft building touches the building is approximately 10 ft.
The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.
The situation forms a right angle triangle.
Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.
Using trigonometric ratios,
let
∅ = angle
tan ∅ = opposite / adjacent
tan ∅ = 6 / 9 = 2 / 3
∅ = tan⁻¹ 0.6666666
∅ = 33.6900672615
Therefore, the height the 15 ft ladder touch building can be calculated as follows:
tan 33.69 = h / 15
h = 15 × 0.66666496431
h = 9.99997446476
h ≈ 10 ft.

The radius of a circle is 3 m. Find its circumference in terms of pi
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!
(btw if pi is something else, use these steps to help you out)
The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.
