WebThe volume of a capsule is calculated by using the formula: = (π * r 2 * h) + (( 4 / 3 ) * π * r 3) Where h is length and r is radius here. Example: A sphere has a radius of 3.5 cm. What will be the volume of the capsule made using this sphere? Consider the length as 30cm. Solution: Step 1: Write the given data. Radius = 3.5cm. Length = 30cm WebApr 5, 2024 · Note: If you need to find the area of the hemisphere, then use the formula, \[2\pi {{r}^{2}}\], where r is the radius. This is the curved surface area. The total surface … WebSo, let us find the volume of a hemisphere which has a radius of 7 units. Step 1: Note the radius of a hemisphere. Here, radius (r) = 7 units.
