Answer:
V = πr²h
To determine the volume of a cylinder you have to multiply the area of the base by the height of the cylinder.
Step-by-step explanation:
The base of a cylinder is a circle. So we must find the area of the circle first. (Which is πr²)
Then we multiply the height by the area of the circle.
V = π·r²·h
This can be used in different ways as well,
if we don't know the radius but know everything else we could use the formula:
(r = √(V/πh))
If we don't know the height we use this formula:
(h = V/(πr²))
Answer: The diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
Step-by-step explanation:
Given: The diameter of Orla's hair strand = 0.005 cm
The diameter of Eduardo's hair strand = 0.012 cm
Clearly , 
The difference between the diameters=
Thus, the diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
It's 64t-3=2t or if your solving for t it's 20.6666666667 so round it to get 21
Step-by-step explanation:
x+x+90=180
2x+90=180
2x=180-90
2x=90
2x/2=90/2
x=45
