Perimeter: 36.84 feet
Let’s start with the easy part...all the rectangle pieces 6 x 3 = 18 feet
We know from subtracting the rectangle length (6ft) from the total length (12 ft) that the diameter of the circle is 6ft.
Circumference = diameter x pi
= 6 x 3.14 = 18.84
We have the circle split into 2 halves, but the circumference remains the same
18 + 18.84 = 36.84
Answer:
86
Step-by-step explanation:
180-94
For this case we observe that the three angles of the triangle are equal. Also, we have by definition:
A triangle is equilateral, when the three sides have the same length (in addition, the three internal angles measure 60 degrees or
.
Answer:
The three sides have the same length
Sec x = 1/Cosx
Pi radians = 180 degress
Pi/12 = 180/12 = 15 degrees.
Sec15° = 1/Cos15°
Sec pi/12 = Sec 15° = 1/Cos 15°
Cos 15° = 0.9659 using a calculator.
Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353
Sec Pi/12 = 1.0353
