Question

Find the volume of the cylinder whose,

a) r= 3.5cm, h = 40cm

b) d=21cm, h = 10cm​

Answer 1

Answer:

ans no 1

$volume \: of \: \: cyinder \\pi r {h}^{2}$

$1 = r = 3.5 \: h = 40 \ \frac{22}{7} \times 3.5 \times 40$

$22 \times 40 \times 0.5 = 440$

$ans \: is \: 440$

ans no 2

$\frac{22}{7} \times 21 \times 10$

$21 \: is \: divided \: by \: 7 = 3$

$22 \times 3 \times 10 = 66 \times 10$

$66 \times 10 = 660$

$ans \: is \: 660$

ans 2
