Answer:
100r^4 + 400r^3 + 600r^2 + 400r + 100
Step-by-step explanation:
Expanding ( r + 1 )^4 gives :-
r^4 + 4r^3 + 6r^2 + 4r + 1
So multiplying 100 with r^4 + 4r^3 + 6r^2 + 4r + 1 gives :-
100r^4 + 400r^3 + 600r^2 + 400r + 100
<em>C</em>≈24.81<em>A</em>=<em>πr</em>2
<em>C</em>=2<em>πr</em>
Solving for<em>C</em>
<em>C</em>=2<em>πA</em>
=2·<em>π</em>·49
≈24.81435
When a number has a negative exponent, that means it's on the wrong side of the fraction bar. So since it is 3^-1 , it is equivalent to 1/3.
So 1/3 is 0.333
And 1/4 is 0.25
1/3 > 1/4
