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.
If r = 13 inches then C = 81.7 inches
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
It is 20.0 and not 19.9
