A Surveyor wants to know the length of a tunnel built three mountain according to equip machines located 212 m from one entrance of the tunnel at an angle of 57° to the perpendicular also equation equipment she is 180 m from the other entrance of the tonight an angle of 40° to the perpendicular based on these measurements find the length of the entire tunnel

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
