Find the volume of a pyramid with a square base, where the area of the base is 12.4 ft” and the height of the pyramid is 5 ft. Round your answer to the nearest
tenth of a cubic foot.

Step-by-step explanation:

Volume of a pyramid is one third the area of the base times the height.

V = ⅓ Ah

V = ⅓ (12.4 ft²) (5 ft)

V ≈ 20.7 ft³

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
