the answer is k=4.6. hope this helps
Answer:
![(x-1)^2+(y+4)^2=9](https://tex.z-dn.net/?f=%28x-1%29%5E2%2B%28y%2B4%29%5E2%3D9)
Step-by-step explanation:
The equation of a circle is given by:
![(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)
Where (h, k) is the center and r is the radius.
The center of the circle is (1, -4).
And the radius is 3.
Substitute:
![(x-(1))^2+(y-(-4))^2=(3)^2](https://tex.z-dn.net/?f=%28x-%281%29%29%5E2%2B%28y-%28-4%29%29%5E2%3D%283%29%5E2)
Simplify. Thus, our equation is:
![(x-1)^2+(y+4)^2=9](https://tex.z-dn.net/?f=%28x-1%29%5E2%2B%28y%2B4%29%5E2%3D9)
Answer:
90 cubes.
Step-by-step explanation:
First we find volume of the cuboid.
Volume = l x b x h = 20 x 18 x 16 = 5760 cm³
Now,
Volume of a single cube = l³ = 4³ = 64
No of cubes that can be cut out from the cuboid is
= Volume of cuboid/ volume of cube
= 5760/ 64
= 90 cubes
