For B, the equation for circumference is pi multiplied by diameter. So, 10 * 2 = 20, and 20*3.14 is 62.8 cm
For C, assuming that "approximate" means that they used 3.14 for pi, then 81.64 / 3.14 = 26, and 26 / 2 = 13 cm

1092...if 4 out of 7 named blue then
1092 * 4/7 = 624 (named blue)
1092...if 1 out of 3 named red then
1092 * 1/3 = 364 (named red)
364 + 624 = 988 (both named red and blue)
1092 - 988 = 104( neither named red nor blue)
answer is 104 people
