WebNov 10, 2024 · A hollow concrete block is defined as a concrete block containing a void area that’s 25% greater than the gross area of the block, with a solid area that should be greater than 50%. Since a hollow concrete block is made from a lightweight aggregate or aggregates, the block will be lightweight, which also these concrete block types easy to … WebJan 5, 2024 · Here, the external radius (R) is 12 cm, the internal radius (r) is 9 cm, and the height (h) is 7 cm. Step 2: We know that the formula to find the area (TSA) of a hollow cylinder is [2πh (R + r) + 2π (R² – r²)] square units. Now, substitute the given values in the formula. Step 3: Thus, the area of a hollow cylinder is calculated as.
