Answer 1

C ≈ 70.4 cm

Explanation:

To calculate the circumference of a circle, you need to know its radius or diameter. The circumference of a circle is the distance around the circle's outer edge. There are two common formulas you can use:

(1) - Using the radius, r:

`\rightarrow \text{Circumference }(C)= 2 \pi r`

(2) - Using the diameter, d:

`\rightarrow \text{Circumference }(C)= \pi d`

In our case, π ≈ 3.142

We are given a radius of 11.2 cm. Using the proper formula we get,

`C= 2 \pi r\\\\\\\Longrightarrow C=2 (3.142) (11.2)\\\\\\\Longrightarrow C=70.3808 \ cm \\\\\\\therefore \boxed{C \approx 70.4 \ cm}`

Thus, the problem is solved.
