The average speed = (speed 1 + speed 2)/2
the average speed = (80/10 + 100/20)/2
the average speed = (8 + 5)/2
the average speed = 13/2
the average speed = 6.5 km/minute
To solve this, set up a proportion. 72/21.6=110/x Cross multiply. 72x=2376. Solve x=33

Step-by-step explanation:
C = 2πr = 53.38cm
r = C / 2π = 53.38cm / 2π = 53.38/ 6.283185307179586 = 8.4956cm
A = πr^2 = π × (8.4956cm^)2 = 226.4cm^2
