Ответ:
hmm
let's experiment with similar thing
wait, I can reverse a known thing
(ab)^n=(a^n)(b^n)
so
(4^7)(9^7)=(4*9)^7=(36)^7
answer is C
Ответ:
153.94
Step-by-step explanation:
c=2r*r
The radius is half of the diameter.
To find the radius you will divide 49 inches by 2.
You should get a total of 24.5
Now that you have your radius you are going to use the circumference formula to solve.
C= 2r*r
C=2(24.5)*(24.5)
type that into the calculator (without the parenthesis) and boom your done!
You answer should be 153.938
then you round to get a total of 153.94
I hope i was able to help!
