6 to 54
6/54
Those are the three ratios
Volume is L×W×H so when you plug in your variables you get 4×4×4 or 60
Hello!
The least common denominator is the lowest common factor between the two denominators
The lowest common denominator is 15
Hope this helps!
Answer:
1018 cm
Step-by-step explanation:
A=piR^2
To find the radius from circumference, we divide by pi and then divide by two.
C=36pi
36pi/pi=36
36/2=18
R=18
if we plug 18 into
A=piR^2,
we get
18pi^2=A
18pi^2=1017.88
round this to get 1018
A=1018
Answer:
a. 1/3pi+kpi and 2/3pi+kpi
Step-by-step explanation:
2Sec²x
=2+2tan²x-(tan²x)²=-1
Let tan²x=u
-u²+2u+2=-1
-u²+2u+3=0
u²-2u-3=0
(u+1)(u-3)=0
u=-1,u=3
(tan x)²=-1(No solution)
(tan x)²=3
>>tan x=±sqrt(3)
I) tan x=sqrt(3)
>>tan(pi/3)=sqrt 3
Tan(pi+A) =tanA
Tan(pi+pi/3)=tan(pi/3)
>>tan(4/3pi)=sqrt(3)
>>x=4/3pi and 1/3pi
General solution: 1/3pi+kpi
ii) tan x=-sqrt(3)
x=2/3pi(At 2nd quadrant)
x=5/3pi(at 4th quadrant)
General solution: 2/3pi+kpi
