The area of the regular octagon is approximately 54 cm2. a regular octagon has an apothem with length 4 centimeters and an area of 54 centimeters squared. line segment a b is a side of the octagon. what is the length of line segment ab, rounded to the nearest tenth? a) 3.4 cm b) 4.8 cm c) 24 cm d) 27 cm

The length of line segment AB = 3.4 cm.

Step-by-step explanation:

Given:

The area of the regular octagon is approximately = 54 cm²

A regular octagon has an apothem with length =  4 cm

AB = side of the octagon

To Find:

AB = side of the octagon = ?

Solution:

A regular octagon has an Eight  equal Side

We Know that,

substituting the given values in equation we get

Now,

     Perimeter = 8 × Side

∴    Perimeter = 8 × AB

∴               27  = 8 × AB

∴    

After rounded to nearest 10th we get

AB =3.4 cm

The length of line segment AB = 3.4 cm.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
