Based on the net shown below, what is the surface area of the pyramid to the nearest square inch. show work

Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
