Answer: 2450.44 ft
Step-by-step explanation:
Formula for SA of a cylinder: A=2*pi*r*h+2*pi*r^2
Formula for radius: diameter/2
Plug height, 17, radius, 13, and pi, 3.14, into the formula above.
= 2450.44 ft
Answer:
300000+50000+5000+600+40+5
word form:- three lakh fifty five thousand six hundred forty five.
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
