Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
When r = 5.05, new volum becomes,
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².
4x + 2y = 56. 5x + y = 34. y = -5x + 34. 4x + 2(-5x + 34) =56. 4x -10x + 68 = 56. -6x = -12. x=2. 4(2) +2y = 56. 8+2y = 56. 2y = 48. y = 24.
x=2, y=24.

Answer: Angle BAD
We don't see the list; it's also called angle DAB.
It would be 7.9 hours all together, so basically eight hours.
