Question

A 8cm long solid is in the form of a right circular cylinder. if its radius is 3.5cm. find the volume of solid

Answer 1

$\huge\mathsf{Given \ -}$

$\mathsf{Height, \ h \ = \ 8 \ cm}$

$\mathsf{Radius, \ r \ = \ 3.5 \ cm}$

$\mathsf{Volume \ of \ cylinder \ =}$ π$\mathsf{r^2h}$

$\mathsf{= \ 22 \ / \ 7 × (3.5)^2 × 8}$

$\huge\mathsf\red{\boxed{= \ 308 \ cm^3}}$

Answer 2

Use the formula pir²h
The volume of the solid will be 308 cm³
