Answer:

DF = 10 units

$m\angle DFG = 28^\circ$

EG = 5.04

Step-by-step explanation:

Properties of Rhombus es

All Sides Of The Rhombus Are Equal.
The Opposite Sides Of A Rhombus Are Parallel.
Opposite Angles Of A Rhombus Are Equal.
In A Rhombus, Diagonals Bisect Each Other At Right Angles.
Diagonals Bisect The Angles Of A Rhombus.

The image contains a rhombus with the following data (assume the center as point O):

DO = 5 units

GF = 5.6 units

$m\angle FEO = 62^\circ$

4. Calculate DF

Applying property 4, diagonals bisect each other, thus the length of DF is double the length of DO, i.e. DF=2*5 = 10:

DF = 10 units

5. Calculate $m\angle DFG$

Applying property 4 in triangle EFO, the center angle is 90°, thus angle EFO has a measure of 90°-62°=28°.

Applying property 5, this angle is half of the measure of angle EFG and angle DFG has the same measure of 28°.

$m\angle DFG = 28^\circ$

6. FG is the hypotenuse of triangle OFG, thus:

$OG^2=FG^2-OF^2$

$OG^2=5.6^2-5^2$

$OG^2=6.36$

$OG=\sqrt{6.36}=2.52$

EG is double OG: OG=2*2.52=5.04

EG = 5.04

What is the surface area of a cylinder with a diameter of 8 centimeters and a height of 12 centimeters?

Lostsunrise [7]

The formula for this is $A=2 \pi rh+2 \pi r^{2}$ . If the diameter is 8 the radius is 4, so filling in accordingly we have $A=2 \pi (4)(12)+2 \pi (16)$ and $A=96 \pi +32 \pi$ which is $A=128 \pi$ and when you multiply in 3.14 you get that A = 401.92 or B above.
