Question

The radius of the circle that surround the star is 5 cm. Which measurement is closest to the circumference of the circle?

Answer 1

31.4cm

Explanation:

According to the scenario, computation of the given data are s follows,

Radius (r) = 5 cm

So, we can calculate the circumference of circle by using following formula,

Circumference of circle = 2 π r

By putting the value in the formula, we get

Circumference of circle = 2 × π × 5

= 10 ×π

= 10 × 3.14

= 31.4 cm

Hence, circumference of circle is 31.4cm.
