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

Answer:

The correct answer option is D. 5.

Step-by-step explanation:

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.
