Find the surface area of the regular pyramid shown to the nearest whole number. the figure is not drawn to scale.
a. 351 m^2
b. 415 m^2
c. 542 m^2
d. 790 m^2

Step-by-step explanation:

Given a regular pyramid we have to find the surface area of regular pyramid.

Side of base(regular hexagon)=13 m

Slant height=l=9 m

Option A is correct.

Option D. 790 m²

Step-by-step explanation:

Surface area of the regular pyramid = surface area of hexagonal base + 6×Surface area of slant triangular side

Surface area of the hexagonal base =

=

= 439 m²

Surface area of slant side =

= 58.5 m²

Surface area of the pyramid = 439 + 6×58.5 = 439 + 351 = 790 m²

Option D. 790 m² is the answer.

a) 7x=7

step-by-step explanation:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
