Answer:
40πcm
Step-by-step explanation:
circ = 2πr
if d = 40cm
r = 20cm
∴ c = 2×π×20
= 40πcm
= 125.66cm

Step-by-step explanation:
Answer:
22 ft.
Step-by-step explanation:
First we can get the total change in elevation, which should be the final elevation minus the initial elevation:
(98ft)-(10ft)=88ft
Then, to get the change in 4 equal intervals, we can divide the total change in elevation by 4.
(88/4)ft=22ft
So during each of the four intervals, assuming they were four equal intervals, the diver descends 22ft.
