We have a bunch of rectangles making up the lateral sides of this figure. They have side length 12 and height 13.
So the area of one rectangle is 12 x 13 = 156.
We have 6 of these rectangles, so our lateral area is 6(156) = 936.
The total surface area requires that we include the area of the base. To find the area of a regular polygon we take half of the product of the apothem and perimeter.
A = (1/2)*a*p
The apothem is given to be 10.39,
and the perimeter is fairly easy to calculate:
With the side length being 12, the perimeter is then 6(12) = 72.
So then the area of our base is (1/2)*10.39*72 = 374.04
So then the total surface area is the (base area) + (lateral area),
374.04 + 936 = 1310.04
Answer:
B
Step-by-step explanation:
bbbbbb brainless me
your Answer is : 27 it may be wrong or good so have fun and i hope i is okay so good luck
Gg easy
point slope:
for opint (x1,y1) and slope m
y-y1=m(x-x1)
so example
(1,2) and slope 3
y-2=3(x-1)
slope intercept
y=mx+b
m=slope
b=y intercept
if slope is 2 and y intercept is 3
y=2x+3
standard form
Ax+By=C
easies of all, just put randome numbers
2x+3y=4
A=2
B=3
C=4
