I dont understand this :( will give brainliest pls help

see explanation

Step-by-step explanation:

Calculate the length of EG in the right triangle using Pythagoras' identity

EG² + 6² = 8²

EG² + 36 = 64 ( subtract 36 from both sides )

EG² = 28 ( take the square root of both sides )

EG = = = 2

tanF = = = =

---------------------------------------------

sec E =  and

cosE = = = , thus

secE = = = ← rationalise the denominator

secE = × =

-------------------------------------------------

cosF = = = =

Step-by-step explanation:

Because ∠G is a right angle, we know that the hypotenuse will be drawn from the two legs and will not touch ∠G.

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
