Answer:
x=11
Step-by-step explanation:
your equation would be
4x+7+39+90=180
136+4x=180
4x=44
We have been given that in a circle an arc length 10 is intercepted by a central angle of 2/3. We are supposed to find the radius of the circle.
We will use arc-length formula to solve our given problem.
, where,
= Arc length,
= Radius,
= Central angle corresponding to arc length.
Upon substituting our given values in arc-length formula, we will get:




Therefore, the radius of the given circle would be 15 units.
Answer:
144
Step-by-step explanation:
Answer: 14 & 8
14 + 8 = 22
14 - 8 = 6
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
