Solutions
To solve the problem the first step is to m<span>ultiply the whole number by the fraction's denominator (4 x 3).Add the numerator (2) to the product.
4 * 3 = 12
12 + 2 = 14
= 14/3 </span>
Radius = 1/2 * diameter = 5
Equation is (x - (-4))^2 + (y - 9)^2 = 5^2
(x + 4)^2 + (y - 9)^2 = 25 is the answer
