The conversion is


So

We're given the fairly unusual

It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.

Ah, there's our .75. The approximate answer is

Third choice.
The exact answer is

also a line through the origin.
Answer:
682
Step-by-step explanation:
620, percentage decreased by - 10% (percent) of its value = 682
givens
pi = 3.14
r = 2
h = 4
Formula
v = pi r^2 h
Sub and Solve
V = 3.14 * 2^2 * 4
V = 3.14 * 4 * 4
V = 3.14 * 16
V = 50.24
By Pythagoras AB^2 = 12^2 - 6^2 = 108
AB = sqrt 108 = 10.39 to nearest hundredth
The perpendicular from M to DC will be parallel and equal to AB so it = 10.39.
Also AB^2 = CB * DB
108 = 6 * DB
DB = 108/6 = 18
so DC = 18-6 = 12
MD^2 = (1/2*12)^2 + 108 = 144
so MD = 12

its B
