Question

Find the volume of a cone if the radius of its base is 1.5 cm and its perpendicular height is 5 cm.

Answer 1

Hey friend, Here is your answer-
R = 1.5 , H = 5
Volume of cone = 1/3 ×pie × r2 × h
= 1/3 × 22/7 × 1.5 × 1.5 × 5
= 82.5/7
= 11.785
~ 11.79 cm3
Volume of cone is 11.79 cm3

Hope it will help you.

$\textbf{\underline{Step-by-step explanation :- }}$

$\textbf{\underline{Solution:}}$Since we know that,

Volume of cone = ⅓ πr²h

Here we have,

Perpendicular height = 5 cm

Radius of base = 1.5 cm

✍️✍️✍️✍️✍️✍️✍️✍️✍️

Volume of cone = ⅓ × 3.14 × (1.5)² × 5 cm³

= ⅓ × 3.14 × 1.5 × 1.5 × 5 cm³

= 3.14 × 0.5 × 1.5 × 5 cm³
