Answer:

82.1

Step-by-step explanation:

So the circumference of the whole circle is 46π.

A quarter of that is 11.5π.

11.5π ≈ 36.1283155163

Simplify that to 1 decimal point: 36.1

Then you add 46 to that.

36.1 + 46 = 82.1

Erin has scanned a 4 × 5-inch postcard, and she wants to reduce it to make a graphic for her Web site. She will use a scale fact

Rasek [7]

Just multiply both dimensions by 2 to make it into centimeters.

Therefore,

4*2 x 5*2 (in inches) will be:

8cm x 10cm (in centimeters)

We conclude that the dimensions of her postcard into a graphic on her web page will be 8x10 in centimeter units.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
