The answer:
the calculus of the circumference depends on what is the value of central angle, so we can take for example 120° the value of the central angle.
<span>since the length of arc ab is 28.61, and the central angle is 120°, we can find the circumference simply by using the following formula:
ARC = Radius x Angle, so Radius = ARC / Angle = 28 .61 / 120° = 0.23 unit
the circumference of a circle is C = 2 x radius x Pie
</span>C = 2 x radius x Pie = 2 x 0.23 x 3.14 = 1.49 unit
6 multiplies by 6.57 gives ya 39.42
Answer:
Step-by-step explanation:
Given
The side of the triangle are
Suppose the third side is
Also, the sum of the two sides of the triangle is always greater than the third
Similarly,
Also,
From (i) and (ii) we get
Answer:
x =5.1
Step-by-step explanation:
For the angle 82, we know the adjacent side and the opposite side
tan 82 = opposite/ adjacent
tan 82 = 36/x
Multiply by x on each side
x tan 82 = 36/x*x
x tan 82 =36
Divide by tan 82
x tan 82/ tan 82 = 36 / tan 82
x = 36/ tan 82
x=5.059470049
To the nearest tenth
x =5.1
