Find the circumference of the circle with the diameter 3.8 cm​

Answer»

Answer:

CIRCUMFERENCE of Circle = 11.932 cm

Area of Circle = 11.3354 cm²

Step-by-step EXPLANATION:

We Have :-

Circle with the DIAMETER 3.8 cm​

To Find :-

Circumference of the circle

Formula Used :-

Circumference\ of\ Circle = <klux>2</klux> \pi r\\\\\\Area\ of\ Circle = \pi r^{2}

Solution :-

Radius\ of\ Circle = \dfrac{Diameter}{2} \\\\\\Radius = \dfrac{3.8}{2} \\\\\\Radius = 1.9 cm

Circumference = 2 * 3.14 * 1.9

                         = 11.932 cm

Circumference of Circle = 11.932 cm

Area = 3.14 * 1.9 * 1.9

                       = 11.3354 cm²

Area of Circle = 11.3354 cm²

Circumference of Circle = 11.932 cm

Area of Circle = 11.3354 cm²
