Conical Frustum -- from Wolfram MathWorld

WebSurface area of a cone = π r (r + l) Solving surface area, SA = 3.14 × 6 (6 + 10) SA = 3.14 × 6 × 16 SA = 301.44 Therefore, Surface area of the right cone is 301.4 sq. cm. Question 2: Calculate the Volume of the right cone for the … WebTotal surface area of frustum of cone = πl [ (R 2 - r 2) / r ] + π (R 2 + r 2) (OR) πL (R + r) + π (R 2 + r 2 ). What are Properties of Frustum of Cone? A frustum of cone has two circular bases and hence two base radii. The distance between the centers of the two bases is the height of the frustum. WebThe circumference of the cone's base=2πr, where r is the radius of the circular base's base. As a result, Curved surface area of cone (CSA) =1 2 ×l×2πr = πrl 1 2 × l × 2 π r = π r l. We know that a cone is made by rotating a right-angled triangle. Pythagoras Theorem helps us find the length of the slant side in a right-angled triangle ... christopher a. wray quotes
