Answer:
(a) = 11 cm
Step-by-step explanation:
The formula for finding the surface area of a regular pyramid is B + (1/2*P*l), with B being the area of the base, p being the perimeter of the base, and l being the slant of the pyramid.
The area of a pentagon can be solved using the formula 1/2*a*p, with a being the apothem and p being the perimeter of the pentagon.
- B + (1/2*80*15) = 1040
- B + 600 = 1040
- 1040 - 600 = 440 (440 is the area of pentagon)
- 1/2*a*(16*5) = 440
- 40*a = 440
- 440/40 = 11
The apothem is 11 cm. Hope this helps!
Answer:
this is just a guess but 81
Step-by-step explanation:
I hope it is right, but I just did quick math.
so it might also be 82 if you round up to the nearest number. (sorry if this is confusing)
6⁻⁷ x 6⁴
= 1/(6⁷) x 6⁴
= 1/(6x6x6x6x6x6x6) x (6x6x6x6)
= 1/(6x6x6)
= 1/(6³)
= 1/216
