Answer: 694.4 in^2

Step-by-step explanation:

We have a cylinder with:

diameter = d = 10 inches

heigth = h = 16 inches.

The total surface of a cylinder is equal to:

S = h*2*pi*(d/2) + 2*pi*(d/2)^2

we can replace the numbers and get:

S = 16*2*3.14*(10/2) + 2*3.14*(10/2)^2 = 659.4 inches squared

Can you factor m3 - 216
Sergio039 [100]

Answer:

Step-by-step explanation:

m³ -216 = m³ - 6³

a³ - b³ = (a-b) (a² + ab + b²)

a =  m  and b = 6

m³ - 6³ = (m - 6)(m² + 6m + 6²)

             = (m - 6)(m² + 6m + 36)

Studentka2010 [4]
It’d be the last (4th) option. x^2+x-6

first you’d subtract 8 from both sides, and then divide by x+2
