❥A cylindrical tank of diameter 21 cm and height 84 cm is filled with milk. How many glasses of diameter 7cm and height 14 cm can be filled with this milk?

⚘Answer࿐

$\small\bf \pink{\fbox\purple{Given}}$

Cylindrical tank with Diameter= 21cm [R=D/2=21/2]

Cylindrical tank with Height= 84cm

Cylindrical Glass with Diameter= 7cm [r=D/2=7/2]

Cylindrical Glass with Height= 14cm

》How many glasses of diameter 7cm and height 14cm can be filled with this milk?

____________________________________________

$\small\bf \orange{\fbox\purple{Solution:}}$

Dimensions of Cylindrical tank:-

Radius = (21/2)cm

Height = 84cm

ㅤㅤVolume of tank=Volume of Cylinder

Volume of cylinder = πR²h

[22/7×(21/2)²×84] cm³

(22/7×21/2×21/2×84) cm³

(8,14,968/28) cm³

⚘29,106cm³

Dimensions of Cylindrical tank:-

Radius = (7/2)cm

Height = 14cm

ㅤVolume of tank=Volume of Cylinder

Volume of Cylinder= πr²h

[22/7×(7/2)²×14] cm³

(22/7×7/2×7/2×14) cm³

(15,092/28) cm³

⚘539 cm³

ㅤㅤㅤSo, Number of Glasses used to fill the tank=

ㅤㅤㅤㅤ(Volume of Cylinder) ÷ (Volume of Glasses)

ㅤㅤㅤㅤㅤㅤㅤ29,106cm³/539cm³

ㅤㅤㅤㅤㅤㅤㅤ=> 54 Glasses

ㅤㅤ❥⚘So, your answer was "54 Glasses"....
