Question

How much water does a cylindrical drum store having radius 3.5 m and height 28 meters. ​

Answer 1

Step-by-step explanation:

here,

radius (r)=3.5m

height(h)=28m

capacity of water stored in drum= Volume of cylinder=

$\pi \: r {}^{2} h \\ = \frac{22}{7} \times 3.5m \times 3.5m \times \times 28m \\ = 22 \times 3.5m \times 3.5m \times 4m \\ = 77 \times 3.5 \times 4 {m}^{3} \\ = 269.5 \times 4 {m}^{3} \\ = 1078 {m}^{3}$

Answer 2

$\huge{\bigstar}$$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

• Volume of cylinder = πr²h

r = 3.5 m .

h = 28 m .

Cylindrical drum storing capacity =

—» 22/7 × 3.5 × 3.5 × 28

—» 22 × 0.5 × 3.5 × 28

—» 1078 m³ .
