How to calculate the surface area of a cone?

There are different objects that you would need to measure, especially in math. It can be complicated sometimes, but as long as you know the formula, it will not be too hard. This time you may want to find out how to calculate the surface area of a cone.

These are the things that you have to do:

• The formula is: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr.

• This means that the surface of the cone is equal to the curved surface area plus the area of the base.

• R will stand for the radius of the base of the cone.

• L will stand for the slant height of the cone.

• The curved surface area is also known as the lateral area.

• Now change the formula to the needed numbers and solve them.

• You can double-check if your answer is correct with the use of an online calculator.

The good thing about most questions in mathematics is that there will be a formula to solve every single one of them. To calculate the surface area of a cone, you will need a formula. Here, the formula that will be used is only when the values of the slant height and radius are known.

1. Solve by using the formula for the surface area of a cone: Here, the formula to use is Surface Area= πrs + πr². From this formula, s represents the slant height, and r is the radius.

2. Replace each parameter with their values: If you have a mathematical problem to solve relating to the surface area of a cone, and you are given the values for radius and slant height, all you need to do is to substitute. For instance, say the slant height is 5cm, and the radius is 2cm. SA= πrs + πr²= 3.14×2×5 +

3.14×(2²)= 31.4 + 12.56= 43.96cm². Note that we used 3.14 as the value of π.
