Answer:
Figure obtained - Cylinder
Surface area of the cylinder is 1224π square units.
Step-by-step explanation:
When a rectangle is rotated about an axis along its largest side, a cylinder having radius 17 and height 19 units is formed.
Surface area of the cylinder = 2πr(h + r)
By substituting r = 17 units and h = 19 units in the given formula,
Surface area = 2π(17)(17 + 19)
= (34)(36)π
= 1224π
Therefore, surface area of the cylinder is 1224π square units.

Answer:
£978
Step-by-step explanation:
i did use a calculator so i don't know if this is wrong or not, sorry if it is.
A. She can multiply the bottom equation by -4 and then add the equations to solve for h.
-4g - 15h = -17
4g - 20h = -52
Add them to get
-15h = -17
-20h = -52
From here, you can solve for h.
