\qquad\qquad\huge\underline{{\sf Answer}}♨

Here's the solution ~

As we know, we can calculate the circumference of a circle in terms of its diameter as :


\qquad \sf  \dashrightarrow \:c = \pi d

where, c = circumference and d = diameter

And also, circumference of circle is terms of radius (r) is :


\qquad \sf  \dashrightarrow \:c = 2\pi r

Now, let's move on to questions ~

First


\qquad \sf  \dashrightarrow \:3.14 * 5.9


\qquad \sf  \dashrightarrow \: \approx18.53 \: ft

・ .━━━━━━━†━━━━━━━━━.・

Second


\qquad \sf  \dashrightarrow \:3.14 * 3.2


\qquad \sf  \dashrightarrow \: \approx10.048 \: ft

・ .━━━━━━━†━━━━━━━━━.・

Third


\qquad \sf  \dashrightarrow \:3.14 * 6.1


\qquad \sf  \dashrightarrow \: \approx19.15 \: ft

・ .━━━━━━━†━━━━━━━━━.・

Fourth


\qquad \sf  \dashrightarrow \:2×3.14 * 3.7


\qquad \sf  \dashrightarrow \: \approx2×11.62 \: m


\qquad \sf  \dashrightarrow \: \approx23.24 \: m

・ .━━━━━━━†━━━━━━━━━.・

Fifth


\qquad \sf  \dashrightarrow \:2×3.14 * 6.2


\qquad \sf  \dashrightarrow \: \approx2× 19.47 \: units


\qquad \sf  \dashrightarrow \: \approx38.94 \: m

・ .━━━━━━━†━━━━━━━━━.・

Sixth


\qquad \sf  \dashrightarrow \:2×3.14 * 5.1


\qquad \sf  \dashrightarrow \: \approx2×16.01 \: ft


\qquad \sf  \dashrightarrow \: \approx \: 32.02m
