What is the first step to find the diameter of the smaller coin?

First step will be option D.

Diameter of the smaller coin will be 2.45 cm

Step-by-step explanation:

Circumference of one coin = 8.03 cm

Circumference of the smaller coin = Circumference of the larger coin - 0.33

                                                         = 8.03 - 0.33

                                                         = 7.7 cm

Circumference of the smaller coin = 2πr = 7.7

r =

r =

r = 1.225 cm

Diameter of the smaller coin = 2 × radius of the smaller coin

                                                = 2 × 1.225

                                                = 2.45 cm

Therefore, first step will be option D.

Diameter of the smaller coin will be 2.45 cm

understand that i don't know the answers

will someone answer his question

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
