Question

What is the formula for finding the surface of a cone
​

Answer 1

Formula for finding the surface area of a cone is shown below

`\pi \: r {}^(2) + \pi \: rl \\ or \\ \pi(r + l)r`

Answer 2

The formula for finding the surface area of a cone is:

Surface area = πr² + πrl

Where:

• π is the mathematical constant pi (approximately 3.14159)

• r is the radius of the base of the cone

• l is the slant height of the cone, which can be calculated using the Pythagorean theorem (l² = r² + h²), where h is the height of the cone
