Use dimensional analysis:
Since we multiplied a numerator and a denominator by centimeters, we are only left with meters.
This answer is already is three significant figures by default.
Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps
Answer:
r = 63 meters
Step-by-step explanation:
C=2πr
We know pi and C
396 = 2*22/7*r
396 = 44/7 *r
Multiply each side by 7/44 to isolate r
396*7/44 = 7/44 *44/7 *r
63 =r
18). 16:80 is the ratio but in simplest form is; 5:0
19). 36:54 is the ratio but in simplest form is; 2:3
20). 12:24 is the ratio but in simplest form is; 1:2
hope that helps:D
When we cube root 123, we get a decimal which rounds out to 4.97. So possible side lengths would be any number greater than that.<span />
