Which equation represents a circle with a center at (-4,9) and a diameter of 10 units?
Dennis_Churaev [7]

Answer:

(x+4)^2 + (y-9)^2 = 25

Step-by-step explanation:

To write the equation of a circle, use the formula (x-h)^2+(y-k)^2 = r^2 where the center of the circle is (h, k).

This means the equation is (x--4)^2 + (y-9)^2 = r^2\\\(x+4)^2 + (y-9)^2 = r^2.

Find the radius r by dividing the diameter of 10 in 2. The radius is 5.

So the equation of the circle is (x+4)^2 + (y-9)^2 = 25

A cylindrical water tank has a radius of 6 feet and a height of 20 feet. A larger tank with the same height has a volume that is
likoan [24]

Answer:

Radius of large cylinder = 10.39 feet\\

Step-by-step explanation:

Volume of the larger tank is three times the volume of smaller tank

Volume of smaller tank

= \pi r^{2} h\\= (3.14) * 6^{2} * 20\\= 2260.8 ft^{3} \\

Volume of larger tank

= 3 * 2260.8 ft^3\\= 6782.4 ft^3\\

Or it can also be written as

\pi r^{2} h = 6782.4 ft^3\\(3.14) * ( r^2) 20 = 6782.4 ft^3\\r^2 = 108\\r = 10.39
