Answer:

$(x-1)^2+(y+4)^2=9$

Step-by-step explanation:

The equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

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:

$(x-(1))^2+(y-(-4))^2=(3)^2$

Simplify. Thus, our equation is:

$(x-1)^2+(y+4)^2=9$

A cone with volume 246 ft cubic if the height is 15 find the radius

Liula [17]

Answer:

r = 3.95 ft

Step-by-step explanation:

Volume of cone = $\frac{1}{3} \pi r^{2} h$ = 246 ft³

246 = $\frac{1}{3} * \frac{22}{7} * r^2 * 15$

r² = $\frac{246*3*7}{22*15*5}$

r = $\sqrt{15.65}$

r = 3.95 ft
