1.

The base of a certain solid is the area bounded above by the graph of y =f(x) =25 and below by the graph of y= g(x)= 16x^2. Cross-sections perpendicular to the x axis are squares.

Use the formula $\displaystyle

V = \int_a^b A(x)dx

$

Thus the volume of the solid is V= ?

2.

To find the length of the curve defined by

y = 2x^2 +3x

from the point (0,0) to the point (1,5), you'd have to compute

$\displaystyle \int_a^b f(x)dx

$

where a = ?

where b = ?

and f(x)= ?

Please Help I am so stuck.

Thanks As always
