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:
f(3) = 4
f(-7) = -26
Step-by-step explanation:
Hi there!

To find f(3), replace every x with 3:

Therefore, f(3)=4.

To find f(-7), replace every x with -7:

Therefore, f(-7)=-26.
I hope this helps!
