Surface Area of Hemisphere Formula: The surface area, $S$, of a hemisphere is determined by the following formula $$S = 3\times r^2\times \pi$$ where $r$ is the length of the radius of the hemisphere and $\pi\approx3.14$. How to Find the Surface Area & Volume of a Hemisphere?
= 235.62 square units The volume of a hemisphere = 2/3 ×π× r3 = 2/3 ×3.14159 × 53 = 2 / 3 × 3.14159 × 125 = 261.8 cubic units Example 2: Find the surface area and volume of the hemisphere if the radius is 12 units and verify it using the hemisphere calculator. ...
hemisphere and we calculate it by using this formula,Surface Area of Hemisphere = 3πr2, where π which is taken as 3.142 or 22/7, and r is the radius of the hemisphere.It should be noted that this is the total surface area of the hemisphere which includes the area of the base too...
