Answer: C. They are equal.
Explanation:
For cone:
Height = 6 units
Radius = 5 units
The volume of cone is given by :-
![V_(cone)=(1)/(3)\pi r^2 h\\\\\Rightarrow V_(cone)=(1)/(3)\pi(5)^2(6)\\\\\Rightarrow V_(cone)==50\pi\ units^3........................(1)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/6ipgejrdm3qwa4gkom05kpv1anwa5if7qh.png)
For cylinder:
Height = 50 units
Radius = 1 units
The volume of cylinder is given by :-
![V_(cylinder)=\pi r^2 h\\\\\Rightarrow V_(cylinder)=\pi(1)^2(50)\\\\\Rightarrow V_(cylinder)==50\pi\ units^3..............(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/uko9iuxz5lf5ao9d4ar1j10sebj92hfdb0.png)
From (1) and (2), we have
![V_(cone)=V_(cylinder)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/iu7zd1166vvf5ckkoeux3s5ikz3fuo7m52.png)
Therefore, the given solids are equal in volume.
