Question

maths, class 8
एन आयरन pole is 4 मीटर हाई एंड 8 सेंटीमीटर एंड डायमीटर फाइंड इट्स हाइट एंड वेट 50 केजी पर मीटर क्यूब ​

Answer 1

↪️Since here above given , basically we have to calculate the volume of the pole and then arrange it to get the weight of it

↪️So as here, Radius "r" = 28/2 = 14 cm = 14/100 =

0.14 mtrs

Height "h" = 4 m

VOLUME OF THE POLE = pi r^2 h

Volume = 22/7 * 0.14 * 0.14 * 4

Volume = 22 * 0.02 * 0.14 *4 = 0.2464 m^3

thus the Volume is = 0.2464 m^3

a thus here , weight = volume x weight per volume

thus , Weight = 0.2464 * 50 = 12.32 kg

Answer 2

Step-by-step explanation:

Since here above given , basically we have to calculate the volume of the pole and then arrange it to get the weight of it

↪️So as here, Radius "r" = 28/2 = 14 cm = 14/100 =

0.14 mtrs

VOLUME OF THE POLE = pi r^2 h

Volume = 22/7 * 0.14 * 0.14 * 4

Volume = 22 * 0.02 * 0.14 *4 = 0.2464 m^3

thus the Volume is = 0.2464 m^3

a thus here , weight = volume x weight per volume

thus , Weight = 0.2464 * 50 = 12.32 kg
