Find the circumference of the circle
The circumference of a circle is equal to
we have
substitute
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
step 3
Find the approximate value of the arc length
To find the approximate value, assume
substitute

Hey there!
You are trying to find the perimeter of triangle ABC. Each side is 2. Since there are 3 sides on a triangle, multiply 2 by 3 to get 6. You do not need the centroid for this problem.
I hope this helps!
Answer:
x = 14
Step-by-step explanation:
let the number be x.
- 4 times the number = 4x
- 10 added to 4 times the number = 4x + 10
now,
- 5 times the number = 5x
- 4 less than 5 times the number = 5x - 4
Given that,
4x + 10 = 5x - 4
moving all x terms to the LHS and the constants to the RHS
4x - 5x = -4 - 10
-x = -14
dividing both sides by -1
<u>x = 14</u>
You can take a million different cross-sections of a sphere and you will always end up with a circle.
Radius= 1/2 • diameter
area of a circle = pie r^2 or (3.14 • radius^2 so u need the diameter this question needs more info
