Question

A right circular cone has base radius 12cm height 5cm find its area of the base​

Answer 1

Answer:

• 204.28 cm²

Step-by-step explanation:

Given

• Radius of cone (r) = 12 cm
• Height of cone (h) = 5 cm

To find

• Area of base/Curved surface area

Solution

↪ Slant height (l) = √r² + h²

• √5² + 12²
• √25 + 144
• √169
• 13

↪ Area of base = πrl

• 22/7 × 5 × 13
• 204.28

∴ Area of base is 204.28 cm²

Answer 2

Answer:

22/7 × 5 × 13

204.28
