Answer:
96
Step-by-step explanation:
IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."
Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π.
π = C
D .
Since D = 2r, then
π = C
2r
or,
C
r = 2π .
arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center. The circumference subtends those four right angles.
arc length
Radian measure of θ = s
r
Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.

Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:
5=−(−z+3)
Simplify:
5=−(−z+3)
5=z+−3(Distribute)
5=z−3
Flip the equation.
z−3=5
Add 3 to both sides.
z−3+3=5+3
z=8
