Answer:
surface area of a cylinder = 188.4 inches²
Step-by-step explanation:
to calculate the surface area of a cylinder given that
height of the cylinder = 9.5 inches
radius = 2.5 inches
recall that the formulae for calculating the surface area of a cylinder = 2πrh + 2πr²
surface area of a cylinder = 2πrh + 2πr²
surface area of a cylinder = 2 x 3.14 x 2.5 x 9.5 + 2 x 3.14 x (2.5)²
surface area of a cylinder = 6.28 x 2.5 x 9.5 + 6.28 x 6.25
surface area of a cylinder = 149.15 inches² + 39.25inches²
surface area of a cylinder = 188.4 inches²
