Question

a cylindrical solid is 40 cm high and has diameter of 2 cm . what is its volume in cm3? give the answer

Answer 1

volume of cylinder is
$\pi {r}^{2} h$
putting the values we get
$\frac{22}{7} .1.1.40 \\ = 125.71 {cm}^{3}$
hope it will help you

Answer 2

Height of the cylinderical solid(h)=40cm

Diameter of the cylinderical solid (d)=2cm

Radius of the cylinderical solid (r)=d/2=1cm

Volume of the cylinderical solid =πr²h

=π×1²×40cm³=125.66cm³
