What is bigger?

Which ball has a larger volume: a football with a circumference of 66 cm or a volleyball with a diameter of 20 cm?

Result

x = (Correct answer is: F) Wrong answer

Solution:

o1=66 cm D2=20 cm  o=πD  D1=o1/π=66/3.141621.0085 cm  D2<D1 V2<V1  x=Fo_{1}=66 \ \text{cm} \ \\ D_{2}=20 \ \text{cm} \ \\ \ \\ o=\pi D \ \\ \ \\ D_{1}=o_{1}/\pi=66/3.1416 \doteq 21.0085 \ \text{cm} \ \\ \ \\ D_{2}<D_{1} \ \\ V_{2}<V_{1} \ \\ \ \\ x=F
