Answer 2

Given ➡

• Volume of the cylinder = 385 cm³

• Height of the cylinder ( h ) = 10 cm

To find ➡

• Radius of the cylinder ( r ) = ?

Formula ➡

• Volume = πr²h

$\huge\mathfb{Solution :-}$

Volume = πr²h

➡ 385 = 22 / 7 × r ² × 10

➡ r² = ( 385 × 7 ) / ( 22 × 10 )

➡ r² = 2695 / 220

➡ r² = 12.25

➡ r = √12.25

➡ r = 3.5 cm

Therefore, the radius of the cylinder is 3.5cm

Solution ➡ Option c that is 3.5 cm is correct .
