The volume of a cylinder = Area of the base × Height of the cylinder = πr²h. Lateral Surface Area = Perimeter of base × height = 2πrh = πdh. Total Surface Area = Lateral Surface Area + Area of bases = 2πrh + 2πr² = 2πr (h+r) Another aspect of cylinders that we must learn is that of a hollow cylinder, like a pipe for example.
Total surface area of a sphere is directly proportional to __ of radius of the sphere. View Solution. Click here:point_up_2:to get an answer to your question :writing_hand:what is total surface area of sphere.
Therefore, The Curved Surface Area of Hemisphere =1/2 × 4 × πr 2. Curved surface area of a hemisphere = 2πr 2. Since a sphere is a combination of a curved surface and a flat base, to find the total surface area we need to sum up both the areas. The flat base being a plane circle has an area πr 2.
In case of an ice-cream filled cone: Total surface area of the Ice-cream cone = Curved Surface Area of Hemisphere + Curved Surface Area of the Cone. Curved Surface area of a hemisphere = 2πr 2 and Curved Surface area of the cone = πrl. So, The Total Surface Area of Ice-cream Cone = 2πr 2 + πrl. Let’s take another example of a tent.
3π. C. 4π. D. 2π. Solution. Verified by Toppr. A steradian is the solid angle subtended at the center of a sphere of radius r by a section of its surface area of magnitude equal to r2. Since the surface area is 4πr2, there are 4π steradians surrounding a point in space.
Question. The surface area of a sphere is 616 cm2. Find the diameter of the sphere (in cm ). Solution. Verified by Toppr. Surface area of sphere=4πr2. According to the statement, 4πr2 = 616. 4× 22 7 ×r2 = 616.
A sphere and a cube have same surface area. Show that the ratio of the volume of sphere to that of cube is √6:√π.
If the radius of a sphere is 12 cm, then find its total surface area . (Take π = 3.14)
