Answer: it’s about 3,600 cubic feet
Explanation:
28–>30
21–>20
6–>6
Now you can do it easily with mental math:
30*20*6=3600
Given area of small circle= πr^²= π×9×9= 81π
and area of greater circle= πr^²= π×11×11= 121π
now area of the sidewalk= area of greater circle (-) area of small circle= 121π-81π=40π
40×22/7=125.714m^²
Answer:
k = 15 option C
Step-by-step explanation:
y ∝ x
y = kx, where k is the constant of proportionality.
when y=210 and x=14, k=?
k=y/x ;
k = 210/14
k = 15
Step-by-step explanation:
344m/s
344 x10 -3)x3600
1238.4km/hr
i hope my answer will help u
