WebJul 1, 2024 · The volume of a pyramid is given by Vpyramid=Abase⋅h3. Since the area of the base of a cone is πr2, the formula for the volume of a cone is Vcone=πr2h3. However, there is a relationship between the volume of a cone and that of a cylinder. What is CSA and TSA of cone? Volume of Cone = (1/3)πr² h. Curved Surface Area (CSA) of Cone = … WebMar 20, 2024 · Curved surface area of a cone is given using the following formula, / (Curved surface area or CSA = πrs/) / (Here, π is a constant which is equal to 3.14 or … WebMar 18, 2024 · Therefore the curved surface area (CSA) of the cone = 616${cm}^2$. Now as we know that the formula of the CSA of the cone = $\pi r'l$ square units, where r’ and l is the radius and slant height of the cone respectively. Now the slant height of the cone is equal to the radius of the circle. Therefore, l = r = 28 cm. Therefore, CSA = $\pi r'l$ chinook dog for sale near me
