Answer 1

`\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`
