Find the volume of a cylinder made by rotating a rectangle with a width of 2.5 feet and a length of 8 feet as shown in the figure. (round to nearest whole number)

the question does not present the picture, but this does not interfere with the resolution

we know that
When a rectangle with a width of 2.5 feet and a length of 8 feet rotates it makes a cylinder with a radius r = 2.5 ft and a height h = 8 ft

volume of a cylinder=pi*r²*h> pi*2.5²*8> 157 ft³

the answer is
157 ft³

The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
