Answer:

408.2cm

Step-by-step explanation:

Given data

Area of base= 25πcm^2

Height= 8cm

Let us find the radius of the cylinder

Area= πr^2

25π= πr^2

25= r^2

r= √25

r= 5cm

Let us now find the surface area

SA=2πrh+2πr^2

Substitute

SA= 2*3.14*5*8+ 2*3.14*5^2

SA= 251.2+ 157

SA= 408.2cm

Hence the surface area is  408.2cm
