Question

find the volume of cylinders
(iii) circumference of base = 1.32 m, height = 25 cm​

Answer 1

Answer:

$circumference = 2\pi {r}$

$2\pi \: r = 1.32$

$r = \frac{132 \times 7}{22 \times 100 \times 2}$

$r = 0.21m$

$r = 21cm$

$volume = \pi {r}^{2}h$

$\frac{22}{7} \times 21 \times 21 \times 25$

$22 \times 21 \times 25 \times 3$

$volume = 34,650 {cm}^{3}$
