Answer:
I think the radius would be 14.28ft
Step-by-step explanation:
Area of circle is pi r^2
Area of circle=641ft
so that means you have to divide 641/3.14 because the point of the question is finding the radius.
so 641/3.14=204.140127
then for the final step finding the square root which is about 14.28ft
that means the radius is 14.28ft.
15:24 is divisible by 3, simplifying it down to 3:8. 19:24, 7:8, and 6:8 are all obviously larger than this ratio, and 1:2 can be equalized to 4:8, which is also bigger than 3:8, so none of the answer choices are less than 15:24.
To round it to the nearest hundreth, round the 6 to the nearest number. 1-4 means round to the lowest number in the chart. 6-10 means round to the nearest number above the current number. The answer would be 4.7
1/4 of 20 is 5.. and 5/10, 3/6, 2/4, 6/12 are all equal to 1/2
