Well this is pretty simple
for the area we need to use the formula A=3.14*radius*radius
so we just plug it in and we get 3.14*8*8 which is 200.96 centimeters squared
for circumference we need to do C=3.14*diameter
to find the diamter we need to do 8 (radius) x 2 which is 16
plugging it in that would be 3.14 * 16 which is 50.24
So in this case the the area is 200.96 and the circumference is 50.24 :)
Answer:
7/16 C.
Step-by-step explanation:
You need to find the common denominator which in this case is 16...it takes 8, two times to get to 16 which 1 times 2 is 2 so therefore it would 5+2 which is 7 and the common denominator stays the same so it would be 7/16.

Answer:
4%
Step-by-step explanation:
After losing 4.17, it came down to 100.08, so the opening price was:
100.08 + 4.17 = 104.25
To find percentage decline, we find the ratio of the "change" (which is 4.17) divided by the opening (original) price, which is 104.25. Then we multiply that fraction by 100 to get our percentage decline.
So,
Thus, the
percentage decline = 4%
As stated in (i), the equation of the line is: ln y = -0.015x + .26
(By the way, I checked your answers for parts (i) and (ii) and they are both correct)
(iii)
Plug in (1.1) for y and solve:
ln (1.1) = -0.015x + .26
0.095 = -0.015x + .26
-0.165 = - 0.015x
10.979 = x
Answer: x = 10.979
