It is 3.485 in the inside and 5.1 at the outside but the answer is <span>0.68333333333</span>
Answer:
B
Step-by-step explanation:
I think your supposed to just count the dots
All you need to do is multiply the two together
12 times 16 = 192 copies
The equation of a circle centred at point (m,n) and radius r is given by
<span>(x-m)² + (y-n)² = r²
</span>-------------------------------------------------------------
Centre = (4,3)
radius = 5
Equation:
(x - 4)² + (y - 3)² = 5²
⇒ x² - 8x + 16 + y² - 6y + 9 = 25
⇒ x² + y² - 8x - 6y + 25 = 25
⇒ x² + y² - 8x - 6y = 0
The equation of the circle is x² + y² - 8x - 6y = 0
Hope it helps!
