Find missing side and find perimeter
Brainiest to first to answer

Missing side = 6.7cm

Perimeter = 42.438cm

Step-by-step explanation:

The missing side will be the diameter of the semicircle

Missing side = 9.2cm - 2.5cm

Missing side = 6.7cm

Perimeter of the figure = Perimeter of rectangle + Circumference of the semi circle

Perimeter of rectangle = 2(L+W)

Perimeter of rectangle = 2(9.2 + 1.5)

Perimeter of rectangle= 2(10.7)

Perimeter of rectangle = 21.4cm

Get the circumference of the semicircle

Circumference of the semi circle= πd

Circumference of the semi circle = 3.14 * 6.7

Circumference of the semi circle = 21.038

Perimeter of the figure = 21.4cm + 21.038cm

Perimeter of the figure = 42.438cm

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.
