I believe the answer is letter D
I think it’s 65 sorry if it’s wrong
A+(-1.3)=-4.5
Add 1.3 to both sides of the equation
a=-3.2
Answer:
72 cubic inches
Step-by-step explanation:
Volume of cone =
--1
Volume of cylinder =
--2
We are given that a cylinder should fit exactly inside the cone
On comparing 1 and 2 we can see:

Since we are given the volume of cone is 24 cubic inches .
So, 


Hence the volume of cylinder is 72 cubic inches
Option D is correct.
