I'm sorry but I know the answer is deffinetly c or d
write question properly bro
Step-by-step explanation:
sec(x) = 1/cos(x)
cot(x) = cos(x)/sin(x)
sec is smaller than cot, if cos is negative (making sec negative) and sin is negative (making cot positive).
and that is true for the third quadrant.
which is pi < x < 3×pi/2
so, the third answer is right.
Answer:
c) The series diverges. There is no sum.
Step-by-step explanation:
A geometric series is a series of the form:
, 
Where:
- First term of the series, dimensionless.
- Common ratio, dimensionless.
A geometric series converges only if 
. As 
, the geometric series diverges. Hence, the right answer is C.
formula is pi*r*(r+sqaureroot(h^2+r^2)
plug in the numbers and the calculated area is 1507.96
but since you cant use fraction or decimals
the answer should be 480PI
