Question

Work out the circumstances of this circle. take π to be 3.142 and give your answer to 1 decimal place. Radius is 4cm

Answer 1

Explanation:

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference, π is pi, and r is the radius.

Substituting the given value of π = 3.142 and r = 4 cm, we get:

C = 2 x 3.142 x 4

C = 25.136 cm

Therefore, the circumference of the circle is 25.1 cm (rounded to 1 decimal place).
