Question

Determine the circumference of the circle. Use 3.14 as an approximation for π.

The radius of the circle is 7 cm.

Please help me out. Thank you.

Answer 1

43.96 cm

Explanation:

The circumference of a circle is given by the formula:

C = 2πr

where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

Given that the radius of the circle is 7 cm, we can substitute this value into the formula and simplify:

C = 2πr

C = 2 × 3.14 × 7

C = 43.96

Therefore, the circumference of the circle is approximately 43.96 cm.
