Examples#1
Ex#1
cones definition :
cones :
Three dimensional figure that goes from a circular base to a triangular point.

v=(pi)r

h/3
v=(pi)3
2
8/3
v=75.4 units cubed
Since r equals three , h equals eight , We just pluged the numbers in the equation and we did 3
2
and we got 9 and then we multiplied (pi) and 9 , which is 28.26 and finally we multiplied 28.26 and 8/3 and got 75.4 units cubed.

v=(pi)r

h/3
v=(pi)5

18/3
v=471 unites cubed
what we did was 5
2
and we got 25. Then we multiplied 25 times (pi) which is 3.14 and it gave us 78.5 . Next we took 78.5 and multiplied it with 18/3 and finally we got 471 unites cubed.

v=(pi)r

h/3
v=(pi)2
10/3
v=41.9 unites squared
We took the radius (2) and squared it ,it got us 4. Then we took that 4 and multiplied it by (pi) which we know equals 3.14 and we got 12.56 . After that we multiplied 12.56 and 10/3 and as the final answer we got 41.9 united squared.

Equation for
cones
Summary slide:
So over all what we basically did was take r (radius) and substitute it with what ever number was on the cone and squared it . After that we multiplied it with (pi) which we know equals (3.14) . Than we got the answer for that . Next we got the number for h (height) and we substitute it to h and we divided it by three and we finally multiplied that with the number we got with (pi) r . And than we got our final answer (unites cubed).
