2 because you can evenly split it in half 2 different ways
The arc length formula is s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).
Here, r = 3.4 cm and the central angle is 46 degrees. We MUST convert this measure 46 degrees into radians, using the conversion factor derived from 180 degrees = pi radians:
arc length = r*theta = (3.4 cm)*(46 degrees)*(pi rad) / (180 degrees) =
2.730 cm (to the nearest thousandth)
=
The answer here would be 0
.................
Let the number he hasn't read yet be X
pages he has read = 3 + ¼x
so 3+¼x +x = 193
5/4x = 193-3 = 190
5x = 190×4 = 760
x= 760÷5 = 152
a. number of pages he hasn't read yet is 152
b if he reads 8 pages in 1 day
then he'll read 152 pages in 152/8 days = 19days
