Answer:
Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.
Step-by-step explanation:
To find the distance , use the formula

If distance < 3, (x, y) lies inside the circle.
If distance > 3, (x, y) lies outside the circle.
If distance = 3 (x, y) lies on the circle.

Answer:
Volume of cone = 200.96 square feet
Step-by-step explanation:
We are given the following information in the question:
The tree is cone shaped and has a radius of 4 feet.
r = 4 feet
The height of the tree is three times its radius.

Volume of tree =

Putting all the values, we get,

Radius of cone whose height is is equal to three times its radius is given as:
![V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \displaystyle\frac{1}{3}\pi r^2 (3r)\\\\3V = 3\pi r^3\\\\ r = \sqrt[3]{\frac{3V}{3\pi}}](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cdisplaystyle%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20h%5C%5C%5C%5CV%20%3D%20%20%5Cdisplaystyle%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20%283r%29%5C%5C%5C%5C3V%20%3D%203%5Cpi%20r%5E3%5C%5C%5C%5C%20r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B3%5Cpi%7D%7D)
Answer:
Last equation 350 - 170 - 120 = r
Step-by-step explanation:
So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!
