Note that (a^b)^c=a^(bc) so in this case we have:

(27^(1/3))^2  the cube root of 27=±3

(±3)^2  and ±3^2=9

So the equivalent expression is 9  or if you need an exponent 9^1 :)

I am assuming that you meant 27^(2/3)

What is the surface area of the cylinder shown below? Use 3.14 for π. A. 660 cm2 B. 863 cm2 C. 353.25 cm2 D. 785 cm2
lesantik [10]

Answer:

602.88cm²

Step-by-step explanation:

Find the image of the cylinder attached

Surface area of a cylinder = A=2πrh+2πr²

r is the radius = 4cm

Height h = 20cm

Substitute

A = 2πr(r+h)

A = 2π(4)(4+20)

A = 8π(24)

A = 192π

A = 192(3.14)

A = 602.88cm²

Hence the surface area of the cylinder is 602.88cm²
