Question

what is surface area of a quarter of cylinder

Answer 1

Therefore, → Total surface area of solid quarter-cylinder = πr(h + r)/2 + Area of two rectangles. → Total surface area of solid quarter-cylinder = π * 10 * (10 + 16) / 2 + 320. → Total surface area of solid quarter-cylinder = 5π * 26 + 320. → Total surface area of solid quarter-cylinder = 5(26π + 64)
