I need help with 10 and 11 please i’ll give brainliest

10) y = -1/2x + 4

11) y = 3x - 1

Step-by-step explanation:

im guessing you needed those in slope intercept form

basically use the points given and the y intercept point given and use the slope formula to find the slope. then put it into the equation

4-3/0-2 = -1/2

-1-8/3-0 = 9/3 = 3

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
