Assuming width=diameter
diameter/2=radius
area=hpir^2
w=d=2
d/2=2/2=1=r
h=6
area=6pi1^2
area=6pi1
area=6pi
aprox pi=3.141592
area=18.85 cm³
21-3= 18 and 18 divided by 6 equals 3 so v=3
He gets 7.80 an hour so you multiply 7.8 by 5.25 hours
Answer:
1/2
Step-by-step explanation:
if you look at a unit circle, sin(\pi/6) is 
so cos of (\pi/6/2) would be \pi/3, and cos of (\pi/3) is 1/2
Answer:
135
Step-by-step explanation:
angle 1 and angle 3 are have the same messure so angle 3 equals to 135
