Pi*radius^2 gives you the circumference of the circle, add the rest of the equation and it’ll give you volume
In the triangle, the remaining angle has measure
. Then by the intersecting secants theorem,

(assuming 102º refers to the measure of arc PK)
A = 54 + 5t
A = 84 + 2t
54 + 5t = 84 + 2t
5t - 2t = 84 - 54
3t = 30
t = 30/3
t = 10....they will reach the same investment in 10 years
