Question

What is the approximate circumference of a circle that has a radius of 10 centimeters? Round your answer to one decimal place.C = ___cm

Answer 1

Answer:

$62.8\text{ cm}$

Explanation:

Here, we want to get the value for the circumference of the circle

Mathematically, we have that as:

$C\text{ = 2}\pi r$

where r is the radius of the circle given as 10 cm

Substituting the value of r, we have that as:

$C\text{ = 2}\times\frac{22}{7}\times10\text{ = 62.8 cm}$
