Question

Hi
I will mark as brain list


the radius of the base of a cylindrical wooden block is 5 cm and its volume is 1100 cu.cm. how many days for of radius 5 centimetre and height in centimetre can be cut from this block of wood


Please tell me answer of this question in easy way but Step-by-step explanation ​

Answer 1

Hi..

radius = 5cm
volume = 1100 cm

volume =

$\pi {r}^{2} h = 1100$

$\frac{22}{7} \times 5 \times 5 \times h = 1100$

$h = 1100 \times \frac{7}{550}$

$h = 14cm$

if h=2cm
r= 5cm

volume of this cylinder =
22/7×5×5×2
=1100/7 cm^2

no. of cylinders = volume of big cylinder/volume of small cylinder
