Question

if the base area of cone is 1.54 sq and its height is 2.4 then the volume of the cone​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Given :-

• Base area of cone = 1.54cm²
• Height of cone = 2.4cm

To find :-

• Volume of cone

Solution :-

★ Base area of cone = area of circle = 1.54cm²

→ πr² = 1.54

→ 22/7 × r² = 1.54

→ r² = 7 × 1.54/22

→ r² = 0.49cm

Now, volume of cone

→ ⅓ πr²h

→ ⅓ × 22/7 × 0.49 × 2.4

→ 22 × 0.07 × 0.8

→ 1.232cm³

Extra Information

• Curved surface area of cone = πrl
• Total surface area of cone = πr² + πrl
