Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
Answer:
0.71428571
Step-by-step explanation:
We can see that for every increment, the number gets
doubled positively. Since we are looking for the value when the repetition is
made infinite, therefore the value at that point would also be infinite. Since
infinite is imaginary, therefore the correct answer is:
<span>Does not exist</span>

Just took the test te only one i got wrong because i put C)0.64
Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.
