Given
centre of circle O(3,2)=O(x0,y0)
point on circle P(6,-2)
Standard equation of circle:
(x-x0)^2+(y-y0)^2=r^2
r=radius of circle
= (distance OP)
= sqrt((6-3)^2+(-2-2)^2)
=sqrt(3^2+(-4)^2)
=sqrt(25)
=>
r^2=(sqrt(25))^2=25
Equation of circle
(x-x0)^2+(y-y0)^2=r^2
(x-3)^2+(y-2)^2=25 ............... standard equation of circle
Answer:
The side length will be 12 and 12
Step-by-step explanation:
6x9=54 then divide it by 2.25 = 24 and divide 24 by 2 = 12 and 12
Answer:
33 ⅓%
Step-by-step explanation:
Percent means out of 100, so write a proportion:
1 / 3 = x / 100
Solve for x by multiplying both sides by 100:
x = 100 / 3
Reduce:
x = 33 ⅓
The percent of questions he got right is 33 ⅓%.
