If r = 13 inches then C = 81.7 inches
13.16 centimeters
If I remember correctly Area of a circle is... PIE multiplied by the RADIUS squared. If this is so.... 15 is the radius and... The sum of 15 x 15 should be multiplied by pie (3.1415 or what ever it is). Use a calculator to get to the nearest tenth.
1.50 rounded to nearest 10th is 1.5.
34.35 rounded to the nearest 10th is 34.4
37.5552 rounded to the nearest 10th = 37.6
Circumference = pi D = 10 pi inchesEach side of the square = (10 pi) / 4 = 2.5 pi = 7.854 inches (rounded)or 7.9 inches, to the nearest 1/10th inch
