Hi, the circled one is what I need help with, thank you :)

The volume of the cone is 26.18 ( round it to the nearest tenth)

The height of the cone is 4

Step-by-step explanation:

Volume: 3.14 x 2.5^2(squared; which means you mst multiply 2.5 x 2.5) x 4 = 26.2(rounded)

Height: 4. It shows it on the diagram of the cone.

Note:

Hope this helps, and let me know if my answer is incorrect, for the other users who will see this message.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
