Question

Find the volume of cone with radius is 2cm and height is 4cm?​

Answer 1

Answer:

16.142cm³

Step-by-step explanation:

V of cone = π r² h/3

= 3.142 × ( 2cm )² × 4cm/3

= 3.142 × 4cm² × 4cm/3

= 3 + 0.142 × 16cm³/3

= 0.142 × 16cm³/3 × 3

( × 3 is cancelled from /3 )

= 16cm³ + 0.142

= 16.142cm³

( Answer may vary because of value of π )
