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

What is the equation of the circle with center (5,-4) and containing the points (5,-2)

gtnhenbr [62]

Answer:

The equation of a circle is $(x-5)^2+(y+4)^2=4$ .

Step-by-step explanation:

-The equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$ (where center is $(h,k)$ , the point $(x_{1},y_{1})$ and the radius known as $r$ ).

-Use the center (5,-4) and the point (5,-2) for the equation:

$(5-5)^2+(-2+4)^2=r^2$

-Solve the equation:

$(5-5)^2+(-2+4)^2=r^2$

$0 + (-2)^2=r^2$

$4 = r^2$

$\sqrt{4} = \sqrt{r^2}$

$2 = r$

-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:

$(x-5)^2+(y+4)^2=2^2$

-Then, after you have the equation, the radius needs to simplified by the exponent:

$(x-5)^2+(y+4)^2=4$
