To find the area enclosed by the curves defined by the parametric equations:

( 𝑥 1 , 𝑦 1 , 𝑧 1 )

( 𝑎 cos ⁡ ( 𝑡 ) , 𝑎 sin ⁡ ( 𝑡 ) , 𝑐 𝑡 ) (x 1 ​ ,y 1 ​ ,z 1 ​ )=(acos(t),asin(t),ct) for 𝑡 t from 0 0 to 10 𝜋 10π ( 𝑥 2 , 𝑦 2 , 𝑧 2 )

( 𝑎 cos ⁡ ( 𝑡 + 𝑔 𝜋 ) , 𝑎 sin ⁡ ( 𝑡 + 𝑔 𝜋 ) , 𝑐 𝑡 ) (x 2 ​ ,y 2 ​ ,z 2 ​ )=(acos(t+gπ),asin(t+gπ),ct) for 𝑡 t from 0 0 to 10 𝜋 10π, where 𝑔
