Answer:
![\large\boxed{x^2+(y-3)^2=2.25}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%5E2%2B%28y-3%29%5E2%3D2.25%7D)
Step-by-step explanation:
The standard form of an equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have the center (0, 3) and the point (-1.5, 3) on the circumference.
The radius is a distance between given points: r = 1.5.
Substitute:
![(x-0)^2+(y-3)^2=(1.5)^2](https://tex.z-dn.net/?f=%28x-0%29%5E2%2B%28y-3%29%5E2%3D%281.5%29%5E2)
Answer:
answer is 20
Step-by-step explanation:
do the math five times four equals 20
I think it is the 3 one from the left side
