Answer:

B. 439.6 $ft^2$

Step-by-step explanation:

The formula for surface area of a cylinder is:

A = 2πrh + 2π $r^2$

A = 2π(5)(9) + 2π $(5)^2$

A = 282.6 + 157

A = 439.6

What number fills in the blank to complete the factorization of 3x + 24? (x + 8)

Crank

we have

$3x+24$

Find the greatest common factor GCF

we know that

$3\\ Factors=1,3\\ \\ 24=2^{3}*3\\ Factors=1,2,3,4,6,8,12,24$

The GCF is equal to $3$

therefore

$3x+24=3*(x+8)$

the answer is

The number is $3$
