Answer:
(x - 16)² + (y - 4)² = 8
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (16, 4) and r = 2, thus
(x - 16)² + (y - 4)² = (2 )², that is
(x - 16)² + (y - 4)² = 8
Answer: $3,664.21
Formula:
- P = principle/original amount = $3000
- r = rate of interest = 4% = 0.04
- t = time period (in years) = 5
- A = the new amount
- e = Euler's number ≈ 2.718...
Substitute in the values:
<u>Approximately $3,664.21</u>

Answer:
13.09 square inches
Step-by-step explanation:
Pie is a circle and area of circle is given by
Total area of pie =
This is divided into 6 equal pieces, so each piece has an area of:
Thus, approximate area of each side (slice) is 13.09 square inches
