Answer :
To find the circumference of a circle, you can use the formula:
[tex]\[ \text{Circumference} = \pi \times \text{Diameter} \][/tex]
In this case, the diameter of the circle is 20 cm, and we are told to approximate [tex]\(\pi\)[/tex] using [tex]\(\frac{22}{7}\)[/tex].
Now, using the formula:
[tex]\[ \text{Circumference} = \frac{22}{7} \times 20 \][/tex]
Let's perform this calculation:
First, multiply 22 by 20:
[tex]\[ 22 \times 20 = 440 \][/tex]
Next, divide 440 by 7:
[tex]\[ \frac{440}{7} \approx 62.857 \][/tex]
This gives us a circumference of approximately 62.857 cm. Since this value does not match any of the provided choices exactly, it suggests there might be an error in the options or calculations, but based on the calculation, the approximate circumference of the circle with the given diameter is 62.857 cm.
