Question

The radius of the circle above is 5 in. What is the circumference of the circle? (Use = 3.14.)

Answer 1

Answer:

31.4

Explanation:

diameter of a circle=2r

d=2×5

d=10cm

therefore, diameter of the circle is 10cm

Circumference of a circle is also known as Perimeter of a circle

thus, Circumference of the circle=πd or 2πr

but here we'll use πd

so, circumference=3.14×10

=31.4cm
