Answer:

The surface area of this cylinder. is <em><u>266π cm²</u></em>

Step-by-step explanation:

Surface Area of Cylinder (SA) = 2πrh+2πr²

since r = 7cm & h = 12 cm

Then SA = 2 π (7)(12) + 2π(7²)

SA = 168π + 98π

∴ SA = 266π cm²

Answer:

The simplified form of the given expression is (2x-1).

Step-by-step explanation:

Consider the given expression is

$\ln e^{2x-1}$

According to the Inverse Properties of In

$\ln e^x=x$

In the given expression the power of e is (2x-1).

Using the Inverse Properties of In, we get

$2x-1$

Therefore, the simplified form of the given expression is (2x-1).
