A cone with a base radius of 10 cm and a height of 18 cm. Find the volume to the nearest whole number

1884

Step-by-step explanation:

To find the volume you have to follow this formula V=πr^2 h/3

Ill type it in words because they plugins look funky.

Volume equals pi times radius squared times h/3

basically you square your radius which is 10 so you get 100

then you multiply that by pi(3.14) now you get 314

you have to divide your height by 3 so you get 18/3 which is 6

so now you multiply 6 by 314 and you get 1884

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
