Question

A cylindrical tank is made of cement material. the thickness of tank is 2cm height is 70cm and inner radius is 100cm . find the volume of cement material used to made the tank.​

Answer 1

$\huge\tt\red{ANSWER√}$

Height (h)= 70 cm

Inner Radius (r)= 100 cm

Outer Radius (R)= 100+2= 102 cm

Volume of cement used

V= π (R²-r²) h

$V = \frac{22}{7} \times ( {102}^{2} - {100}^{2} ) \times 70 \\ \\ \frac{22}{7} \times 404 \times 70 \\ \\ \frac{622160}{7} \\ \\ = 88880 \: c {m}^{2} \: \: ans. \\ \\ hope \: \: it \: \: helps \\ \\ mark \: \: brainliest \: \: pls$
