For the solid line it is (0,-3), (0,3), (-3,4)
for the dotted line it is (-1,-1), (-3,-2), (-3,2)
hope this helps don't know for sure though if its right i just did the best i could do.
(a) 64
divide 16 by .25 and you will get 64
(b) 34
multiply 40 by .85
Cylinder: First you need to find the radius. To do that, you need to divide the diameter by 2
Then, you multiply it by itself
After that, you multiply it by the height
And finally multiply it by pi
Cone: First, you need to find the radius dividing the diameter by 2
Then, multiply it by itself
After that, divide the height by 3
Finally, multiply the radius times the height and then multiply it by pi
The answer to the cylinder is 251.2 and the answer to the cone is 251.2
The processes are the following:
Cylinder
D:8
R:4
V:π4^2*5
V:π16*5
V:80π
V:251.2
Cone
D:8
R:4
V:π4^2 15/3
V:π16*5
V:80π
V:251.2
Answer:
I don't really know how to show the work for this one but the answer should be 13 because angle CA is 8 too if Angles CA were to be rotated on to the X line BC it would like be almost about the same size as Anglesey are whatever and that what it would be like a few inches or whatever a few inches longer I guess
is
