20%
This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
Answer:
The Answer is B
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 diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
Well first you take 78 and turn it to 7.8
then multiply by 10000
therefore 7.8*10000= ?
