Answer:

$84^{\circ}$

Step-by-step explanation:

The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:

$2(7x-7)=9x+21$

Solving, we get:

$2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7$

Plugging in $x=7$ into $9x+21$ :

$\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}$

Lets get started :)

The area formula of a cylinder is:
Area = $2(radius)^2+2 \pi (radius)(height)$

We are given:
The radius: 6 units
The height: 15 units

Apply the formula!

A = $2 \pi (6)^2+2(6)(15)$
= $72 \pi + 180 \pi$
= $252 \pi$ units²

Your answer will be option D
