Hello!
where la is lateral surface area
Answer:
third option
Step-by-step explanation:
Given the arithmetic sequence
14, 24, 34, 44, 54, ....
with f(1) = 14 and common difference d = 24 - 14 = 10
The recursive function allows a term in the sequence to be found by adding d to the previous term, thus
f(n + 1) = f(n) + 10 where f(1) = 14
Cute one!

</span>Summarizing:
<span>sec(acot(tan(asin(sin(pi/3)))) .... use asin(sin(x))=x
</span>=sec(acot(tan(pi/3)))
=sec(acot(sqrt(3))) ......... use acot(x)=atan(1/x)
=sec(atan(1/sqrt(3)))
=sec(atan(sqrt(3)/3)) .... evaluate atan(sqrt(3)/3), use unit circle
=sec(pi/6)
=1/cos(pi/6)...... evaluate cos(pi/6), use unit circle
=1/(sqrt(3)/2)
=2/sqrt(3) .... now rationalize
=2sqrt(3)/3
