Answer:
Question 2: A. Overlapping lines.
The equations are identical; and if we would treble the first equation, we get the second equation.
Question 3: B. Multiply the second equation by -3 to get
arc length = radius multiplied by angle in radians
radius = 7 angle = 90 degrees
90 degrees = 1.571 radians
7 × 1.571 = 10.997
AB is 10.997 or 11 inches long
Answer:
π2,√80,12
Step-by-step explanation:
π2= 6.28
√80= about 8
12=12
Hope I could help!
Answer:
65.82
Step-by-step explanation:
The reference angle we are using is the 60 degree angle, therefore n is the opposite.
We have the adjacent side as 38. So we can use this equation
tan(60) = 38/x
38 * tan(60) = 65.8179306876 or 65.82
You are very welcome!

Answer:
Step-by-step explanation:
First, you need to make these conversions:
(Remember that )
4,000 cm to m:
700 cm to m:
You can observe in the figure that it is formed by two rectangles and a semi-circle.
To calculate the perimeter, you need to add the exterior measures of each figure.
Remember that the circumference of a circle is:
Where "r" is the radius
Therefore, the perimeter is:
To find the area of the indoor sports exhibition, you need to add the areas of the rectangles and the area of the semi-circle.
The area of a rectangle can be calculated with:
Where "l" is the lenght and "w" is the width.
The area of a semi-circle can be calculated with:
Where "r" is the radius.
Then, the area of the indoor sports exhibition is:
