Question

find the volume of a cylinder having radius of the base 1.4 cm and height 10 cm

Answer 1

Its answer is 61. 6cubic cm

Answer 2

We know that the volume of a cylinder is
$\pi {r}^{2} h$
here, r=1.4 cm
h= 10cm


so, its volume is
$\frac{22}{7} \times {1.4}^{2} \times 10$


$\frac{22}{7} \times \frac{196}{100} \times 10 \\ \frac{22 \times 28}{10 } \\ 61.6$
therfore its volume is 61.6 cubic centimeteres
