Answer:
5,538.96 in
Step-by-step explanation:
A=π r^2
Remember r^2 is r * r.
r^2 = 42*42= 1,764
A= 3.14 * 1,764 = 5,538.96in
A =5538.96 in^2
The area of a circle is given by
A = pi r^2
We know the radius is 42 and pi is approximated by 3.14
A = 3.14 * 42^2
40%
Make it so the denominator is 100 since a percentage is out of a 100.
2/5 x 20/20 = 40/100
Now turn 40/100 into a percent. Should be simple. 40 out of 100 is 40%.
25\100*500=125
1/3*125=41.66
41.66 millilites is left in the bottle
