Answer:
C
Step-by-step explanation:
The volume of a cone is given by
The volume of a cylinder is given by
<em>Where h is the height and r is the radius</em>
The first figure is a cone with height 6 and radius 5, we can put it into the formula and find the volume:
The second figure is a cylinder with height 50 and radius 1, we can put it into the formula and find the volume:
We can see that they are equal. So answer choice C is right.
-3(5-6)-4(2-3)
Handling parentheses first:
-3(-1)-4(-1)
Multiplication left to right:
3-4(-1)
3-(-4)
Rewriting the above we have:
3+4=7
