I need help with how to solve these using code(i.e. Python)

8. Two ladders crisscross an alley of width W. Each ladder reaches from the base of one wall to some point on the opposite wall. The ladders cross at a height H above the pavement. Find W given that the lengths of the ladders are x1 = 20 ft and X2 = 30 ft, and that H = 8 ft. 9. A can in the shape of a right circular cylinder is to be constructed to contain 1000 cm. The circular top and bottom of the can must have a radius of 0.25 cm more than the radius of the can so that the excess can be used to form a seal with the side. The sheet of material being formed into the side of the can must also be 0.25 cm longer than the circumference of the can so that a seal can be formed. Find, to within 10-4, the minimal amount of material needed to construct the can. X2 x H W + 0.25 h 8. Two ladders crisscross an alley of width W.
