Find the area of the surface generated when the given curve is rotated about the x-axis. y = 4 squareroot x on [60, 77] The area of the surface generated by revolving the curve about the x-axis is square units. (Type an exact answer, using it as needed.)

A≅562.45π u²

Step-by-step explanation:

Knowing that the volume the a solid is V=πR²h, then A=πR², therefore

A=π(4√x),  integrating on both sides ∫A=4π∫√xdx ⇒ ∫√xdx =

evaluated (60,77), then

- 70

this is the answer for you hope it

probability for j is 1/4

while

a is 1/6
