The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle

Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5

So, 2×3.14(π)×3.5=21.98

<u>Answer:</u>

The correct answer option is D. 5.

<u>Step-by-step explanation:</u>

We are given the following expression where 4 is to be divided by a fraction 1/5:

4 ÷ \frac{1}{5}

This can also be written as:

\frac{4}{\frac{1}{5} }

Now to find the quotient of this, we will take the reciprocal of the fraction in the denominator to change it into multiplication.

4 \times \frac{5}{1}

Therefore, ignoring the 1 in denominator, we can simply multiply 4 by 5.
