Question

find the volume of the right circular cone with radius 3.5 cm , height 12 cm​

Answer 1

Solution

Given :-

• Radius of right circular cone = 3.5 cm
• Height = 12 cm

Find :-

• volume of right circular cone

Explanation

Using Formula

★ volume of right circular cone = π r²h/3

Where,

• π = 22/7

Now, Keep all above values.

➡volume of right circular cone = 22/7 × (3.5)² × 12 /3

➡volume of right circular cone = 3.5 × 3.5 × 4 ×22/7

➡volume of right circular cone = 20 × 3.5 × 22

➡volume of right circular cone = 7 × 22

➡volume of right circular cone = 154 cm³

Hence

• volume of right circular cone = 154 cm³

Answer 2

Answer:

formula is πr²h

Step-by-step explanation:

1. =π(3.5)²×12/3
2. =22/7 ×35/10×3.5×12/3
3. =22/1×5/10 ×3.5×12/3
4. =22×1/2×3.5×12/3
5. =22×1/1×3.5×6/3
6. =22×3.5×6/3
7. =462/3m³
8. =154m³
