Please help! 12. Find the surface area of a cylinder that has a helght of 65 feet and a radius of 26 feet. Show your work.​

A ≈ 14866.02

Step-by-step explanation:

A=2πrh+2πr2=2·π·26·65+2·π·262≈14866.01644

I hope this helps :)

Step-by-step explanation:

Cylinder can be divided into 2 circles and 1 folded rectangle.

C = 2πR = 52π feet

A = πR^2=676π feet^2

52π * 65+676π * 2 = 4732π= 14866.02 feet^2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
