Answer:

D: 109 cm

Step-by-step explanation:

The formula of circumference is

[tex]\pi d[/tex]

Diameter =

[tex]17.4 \times 2 = 34.8[/tex]

Hence, circumference =

[tex]34.8 \times \pi = 109.32742...[/tex]

rounded of to 109.

Answer:

circumference of a circle = 109.272

so correct option is D. 109 cm

Step-by-step explanation:

given data

circle radius = 17.4 cm

to find out

What is the circumference of the circle

solution

we will apply here formula for the circumference of a circle that is express as

circumference of a circle = π × d    .........................1

here d is diameter of circle

and we know diameter = 2 × radius

put her value of radius we get diameter

so diameter d = 2 × 17.4 cm

diameter d = 34.8 cm

put these value in equation 1 we get

circumference of a circle = 3.14 × 34.8

circumference of a circle = 109.272

so correct option is D. 109 cm
