Can someone help me answer this please

Hey there! :)

1639.08 in².

Step-by-step explanation:

We can find the surface area of the cylinder using two formulas:

Bases:

A = πr²

Lateral area:

A = π2rh

Begin solving for the area of the bases:

A = π(9)²

A = 3.14 · 81

A = 254.34 in².

There are two circular bases in a cylinder, therefore:

254.34 × 2 = 508.68 in².

Solve for the lateral area:

A = π2rh

A = 3.14 × 2(9) × 20

A = 3.14 × 18 × 20 = 1130.4 in²

Add up both of the areas:

508.68 + 1130.4 = 1639.08 in².

The Surface Area of this cylinder is 1639.08 in².

step-by-step explanation:

sorry i just needed points for a quiz plz for give me

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
