Question 15 If two solid hemispheres of same base radius r are joined together along their bases the curved surface area of this new solid is (A) 4 π r 2 (B) 6 π r 2 (C) 3 π r 2 (D) 8 π r 2 View Solution
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.
Curved Surface area of a hemisphere = 2 π r 2 = 2 × 22 7 × 21 × 21 = 2772 c m 2 Total surface area of a hemisphere = 3 π r 2 = 3 × 22 7 × 21 × 21 = 4158 c m 2 Was this answer helpful?

The total surface area of a solid hemisphere is 675 π sq. cm. Find the curved surface area of the solid hemisphere. Find the curved surface area of the solid hemisphere. Open in App
Oct 16, 2023 · The curved surface area of a hemisphere is given by: Curved Surface Area = 2πr² where "r" is the radius of the hemisphere. So, rearrange the formula to find "r": 2πr² = 154 r² = 154 / (2π) r² ≈ 24.5 r ≈ √24.5 r ≈ 4.9497 (rounded to four decimal places) 2. Now that you have the radius, you can find the volume (value) of the ...
