Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
17.6 is the diameter so divide that by 2 to get the radius which is 8.8
(1/3)π(8.8²)(23.4) = (1/3)π(77.44)(23.4) = (1/3)π(1812.096) = (604.032)π
if you need a more specific answer and pi can equal 3.14 then it equals 1896.66048
Answer:
slope is -2 and the y-intercept is 12
Step-by-step explanation:
a key thing to remember: x is always equal to 0 when finding the y-intercept.
so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12.
to find the slope use the equation: slope= change in y/change in x
you can use any two points to find this.
lets take the points of the x-intercept (6,0) and the y-intercept (0,12)
12-0/0-6
12/-6
-2 = slope
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
