The total surface area of a cylinder is 220 sq. cm with height 6.5 cm. Find its volume

25.025 cm3 2.5025 cm3 2502.5 cm3 250.25 cm3

250.25 cm3

TSA = 2πr(r + h)220 = $2×\frac{22}{7}×r(r+\frac{13}{2})$ $⇒r=-10,\frac{7}{2}$ Since radius cannot be negative $∴r=\frac{7}{2}$ ∴ πr2h = 250.25 cm3 Hence, volume of the cylinder = 250.25 cm3
