Question

The area of base of a cone is 110cm square and the total surface area of the cone is 250 cm square. Find the curved surface area.​

Answer 1

The curved surface area of the cone is 140 cm², found by subtracting the base area from the total surface area.

Step-by-step explanation:

To find the curved surface area of a cone when given the area of the base and the total surface area, we can use the following method:

1. First, we need to understand that the total surface area of a cone consists of the base area and the curved surface area.
2. Since we know the base area is 110 cm² and the total surface area is 250 cm², we can subtract the base area from the total surface area to find the curved surface area.
3. Subtracting, we get 250 cm² - 110 cm², which equals 140 cm².

Therefore, the curved surface area of the cone is 140 cm².
