The triangular pyramid is made up of four congruent triangles. The surface area is approximately 250 square meters. D
B
Which could be the dimensions of the base and the height of the triangular base of the pyramid?
o 1= 12 m; h= 10.4m
O = 14m, n= 12.1m
O /= 24 m; h= 20.8m
O = 28m, h= 24 1 m

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04

step-by-step explanation:

ur welcome : )

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

apex answer is: true.
