Find the diameter of circle Z if the center has coordinates (0, 2) and a point on the circle is (3,4).

Diameter of the circle = 2√13

Step-by-step explanation:

The radius is calculated by using the formula for calculating the distance between the two points as shown;

R = √(y2-y1)²+(x2-x1)²

Given the coordinates (0, 2) and (3,4)

R = √4-2)²+(3-0)²

R = √2²+3²

R = √4+9

R = √13

Diameter = 2R

Diameter of the circle = 2√13

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

m∠a is 90°

m∠b is 40°
