The equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625
<h3>Equation of a circle</h3>
The formula for finding the equation of a circle is expressed as:
(x-a)² + (y - b)² = r²
where
(a, b) is the centre
r is the radius
Given the following
(a, b) = (0, 0)
r = 12.5/2 = 6.25
Substitute
(x-0)² + (y - 0)² = 6.25²
x²+y²=39.0625
Hence the equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625

Answer:
The answer is 17
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- a² – 4b + 2c
- a = 1, b = (-3) and c = 2
<h3><u>To </u><u>Find</u>;</h3>
- The value of a² – 4b + 2c
Now, Evaluate
a² – 4b + 2c
(1)² – 4(-3) + 2(2)
1 + 12 + 4 = 17
Thus, The value is 17
