Answer:

1. The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20.

2. The total surface area of a cone is the sum of the area of its base and the lateral (side) surface. The lateral surface area of a cone is the area of the lateral or side surface only. Since a cone is closely related to a pyramid , the formulas for their surface areas are related.

4. The formula to calculate the total surface area of the cone is: TSA of cone = πr2 + πrl = πr(l+r) square units.

Surface Area Of Cube: Square Root Of 7

5. The formula for the area of a cone is 3.14 times the radius times the side (πrl)
