The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.

Find the value of m ÷ n if m = 1 1/4 and n = 3

Musya8 [376]

M ÷ n
m = $\frac{11}{4}$
n = 3

$\frac{11}{4}$ ÷ 3
Multiply $\frac{11}{4}$ by the reciprocal of 3 which is $\frac{1}{3}$

= $\frac{11}{4}$ × $\frac{1}{3}$
= $\frac{11*1}{4*3}$
= $\frac{11}{12}$
