Question

Find the volume of the cylinder whose radius is 0.7cm and height +1.4cm

Answer 1

volume of cylinder = πr^2h

= π(0.7)^2×1.4

= π0.49×1.4

= π 0.686 cm^3

if we put the value of π

=(22/7)×0.686

=15.092/7

=2.156cm^3

=2.16cm^3

hope this will help you❤❤❤

Answer 2

Answer:

if r=0.7

h=1.4

$v = \pi {r}^{2} h \\ = 3.14 \times ( {0.7}^{2} \times 1.4 \\ = 2.15404$

I hope it will help you
