Answer:
c. 105 yd^2.
Step-by-step explanation:
First find the slant height (h) of each of the triangular walls:
tan 60 = h / 3.1
h = 3.1 tan 60
= 5.369 yds.
Area of each side = 3.1* 5.369
= 16.645
Total surface area of the pyramid
= 4 * 16.645 + 6.2^2
= 105.02 yd^2.
Step-by-step explanation:
30 1/3 = 91/3
3 × 91/3% = 91/100 (0.91)
(3-0.91=2.09) < I dunno if you need to subtract it tho^^
Answer: C
Step-by-step explanation:
is dotted and shaded below, so it represents 
.
Also, 
is shaded above, so it represents 
.
The volume of the prism stays the same, but the number representing the volume increases because cubic meters converted to km is 1e-9
I'm pretty sure the answer would be 4+4x
