We must use a certain formula to find the circumference. The formula for circumference of a circle is:

C = 2 * pi × r

Substitute:

C = 3.14 × 6.1 × 2

C = 38.303

Round to the nearest tenth:

38.3.

ANSWER:

The circumference of the circle is about 38.3 centimetres.

What is the Area of the circle in pi units if the diameter is 6 cm?
sergejj [24]

The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

<h3>What is the area of the circle?</h3>

The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,

A=\pi\dfrac{d^2}{4}

Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.

d=6

Put this value in the above formula to find the area of the circle as,

A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm

Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
