Answer: surface area of the cylinder is 207.24cm^2
Step-by-step explanation:
Surface area of a cylinder is calculated by A=2πrh+2πr2
Where π is a mathematical constant given as 3.14
r is radius given as 3cm
h is height, given as 8cm
rh = 3cm × 8cm = 24cm^2
r^2 = 3cm × 3cm = 9cm^2
Slot the values into the formula
A = (2 (3.14) 24) + (2 (3.14) 9)
A = (6.28 x 24) + (6.28 x 9)
150.72 + 56.52
A= 207.24cm^2
