The sector area is = pi * r^2 (circumference/360). Do the work inside the () first and then multiply by pi r^2
Answer:
Base = 16 inches
Step-by-step explanation:
A triangular Bandana has an area of 70 square inches
The height of the triangle is 8
Area of a triangle is given by;
× base × height
∴
× base ×
= 70
base =
inches
Essentially, 50% of $10.56 is $5.28.
This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>
Side note: Another way that you can do this is by simply doing 1.5(10.56).
The two colors can be chosen in 3 different ways.
<h3>
In how many ways can we choose two colors?</h3>
If we have a set of N elements, the number of different sets of K elements (such that the order of the K elements does not matter) is:

In this case, we have 3 colors, so N=3, and we want to choose 2, then K=2.
Replacing that we get:

The two colors can be chosen in 3 different ways.

Answer: Gustavo is 261.96 meters away from Aiden. Or Aiden is 261.96 meters away from Gustavo.
Step-by-step explanation: From the question, considering a North, East, South and west pole, Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal.
Therefore, Where a and b are distances travelled respectively by Gustavo and Aiden. While θ is the angle between them.the total angle between them is 23 + 33 = 56°. Therefore, let the distance between them be c and we can calculate that using the cosine law.c² = a² + b² – 2ab cos θ. Therefore, let the distance between them be c and we can calculate that using the cosine law.c² = a² + b² – 2ab cos θ.
Therefore, they are 261.96 meters apart.
c² = 300² + 250²– 2(300) (250)cos 56
c² = 90000 + 62500 - 83878.9355
c² = 68621.0645
c = √68621.0645
c = 261.96 m
