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.
The surface area of a sphere of radius 14 cms is. View Solution. Q4. Find the surface area of a sphere of ...
Assertion :When a sphere is cut along the diameter into two hemispheres, the total surface area increases. Reason: Total surface area of a hemisphere is equal to the addition of the curved surface area of the hemisphere and the area of circle of same radius.

The volume of a sphere is 38808 cm 3.Its curved surface area is (a) 5544 cm 2 (b) 8316 cm 2 (c) 4158 cm 2 (d) 1386 cm 2
The surface area of a sphere is same as the curved surface area of a right circular cylinder whose height and diameter are 12 cm each. The radius of the sphere is: The radius and height of a right circular solid cone are 7cm and 24cm respectively. Find its curved surface area (in cm2)
A right circular cylinder just encloses a sphere of radius r (see figure). Find the (i) surface area of the sphere, (ii) curved surface area of the cylinder and (iii) ratio of the surfaces obtained in (i) and (ii).
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.
