the formula for the circumference of a circl is c = 2 nr determine the circumference when the radius r is 10 cm

Sagot :

Answer:

20π cm or approximately 62.8 cm

Step-by-step explanation:

» Concepts

The circumference of a circle is the distance, or perimeter, around a circle in a certain unit such as centimeters. The formula to find the circumference, as stated, it 2πr, where r = radius.

» Application

In this case, we're asked to find the circumference of the circle using the formula 2πr. We're also given the radius as 10 cm.

» Solving

  • [tex]2(10)\pi[/tex]
  • [tex]20\pi[/tex]
  • 20π cm

or

  • [tex]2(3.14)(10)[/tex]
  • [tex](6.28)(10)[/tex]
  • [tex]62.8[/tex]
  • 62.8 cm

Answer:

c=2nr

but r=10 and n=3,14

c=2(3,14)(10)

c=62,8
