Question

If the radius of a circle is 4.2 cm, compute its area and circumference..​

Answer 1

Area of a circle = πr2

So, area = π(4.2)2 = 55.44 cm2

Circumference of a circle = 2πr

So, circumference = 2π(4.2) = 26.4 cm

Answer 2

Answer:

The circumference and area of the circle is 26.4 cm2 and 55.44 cm2.
