Step-by-step explanation:
I just did it and got it correct
Since we're looking for the rate of kilograms per minute, we can represent the rate as
. We just need to divide the kilograms crushed by the time it takes to crush them to obtain R:
Answer:C = 2 π r
r = C / 2 π
r = 907.46 / 2 π
r= 144.42
Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units
Step-by-step explanation:
Rewrite it as
3r-1=8
3r=8+1
3r=9
R= 3
