WebMar 28, 2024 · To calculate the volume of a cone, start by finding the cone's radius, which is equal to half of its diameter. Next, plug the radius into the formula A = πr^2, where A is the area and r is the radius. Once you have the area, multiply it by the height of the cone. Finally, divide that number by 3 to find the volume of the cone. WebThe surface area S of a cone is given by the formula. S = π r 2 + h 2, S = \pi \sqrt { r ^ { 2 } + h ^ { 2 } }, S = π r 2 + h 2 , where r is the radius of the base and h is the height. What is the approximate height of a cone with a surface area of 40 square inches and a base radius of 8 inches? A. 5 inches B. 10 inches C. 15 inches D. 20 inches
