Find the volume of the cylinder.<br> Either enter an exact answer in terms of π or use 3.14 for π

Alex787 [66]

Answer:

Volume of the cylinder = $62.80 units^3$

Step-by-step explanation:

Height of the Cylinder(h)=5 units

Radius(r)=2 units

Volume of a cylinder= $\pi *r*r*h$

Putting the values in the formula;

Volume of the cylinder $=\pi *2*2*5$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cylinder= $3.14*2*2*5$

$=3.14*2*2*5\\\\=3.14*4*5\\\\=3.14*20\\\\=62.80units^3$

The Volume of the cylinder is $62.80 units^3$

Note angles not necessarily drawn to scale

kondaur [170]

Answer:

Step-by-step explanation:

Angles CGE and 30° are vertical angles.

Thus, Angle CGE is thus 30°.

Angle CGE and Angle x are complementary, so x = 90° - 30° = 60°
