The surface area of a cylinder can be found using the expression 27r(h+ r). Find the surface area of the cylinder
shown. (Use 3.14 for 7 and give your final answer rounded to the
nearest tenth.)

188.4 ft^2

Step-by-step explanation:

Given, r= 3 ft, h= 7ft, pi = 3.14

Using the equation,

Surface area of cylinder= 2* pi * r (h+r) = 2* 3.14* 3 ft ( 3+7) ft = 188.4 ft^2

answer: ouch. thats difficult

step-by-step explanation:

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
