Answer:
The radius of cylinder is 8 inches.
Step-by-step explanation:
We have given,
Volume of cylinder = 320π cubic inches
Height of cylinder = 5 inches
We know, Formula for volume of cylinder as : V =πr²h
where r is radius of cylinder and h is the height of cylinder.
So, We can plug values for V and h to get radius of cylinder.
i.e V = πr²h
320π = πr²* 5
Solving for r.
We get,
320 = r² * 5
320/5 = r²
64 = r²
or r = ±8 , Since radius of cylinder can not a negative number so we neglect -8.
Hence the radius of cylinder is 8 inches.
Answer:
125
Step-by-step explanation:
( 3x - 70 ) is exterior angle.
60 and x are interior angles.
Formula : -
Exterior angle of a triangle
= Sum of two interior angles in a triangle
3x - 70 = x + 60
3x - x = 60 + 70
2x = 130
x = 130 / 2
x = 65
m∠LKM = 3x - 70
= 3 ( 65 ) - 70
= 195 - 70
m∠LKM = 125
